气相色谱仪电子捕获检测器(ECD)使用手册

气相色谱仪电子捕获检测器（ECD）使用手册1 结构电子捕获检测器组块为一个独立的整体，可以拆换。

它和快速进样汽化室组合，可以实现全玻璃系统。

检测器采用单极输入、输出方式，即脉冲极化电压经信号线加在离子室阳极上。

其结构示意图见图7-1。

图7-1 ECD结构示意图2 原理GC-4000A型气相色谱仪配备的电子捕获检测器属于高灵敏度高选择性检测器，它对电负性物质（如氯化物）特别敏感。

例如：对γ-666可测出10-13g，它可广泛应用于环境保护，食品检验和医药卫生等部门。

ECD是放射性离子化检测器的一种。

当载气进入检测器时，室内的放射源发射的β射线，使载气（N2）电离而产生自由电子，此时检测器的电子流表示池体内存在的自由电子浓度，这个电流也就是我们所说的基流。

色谱柱馏出物进入检测器，能吸收电子的被分析物和池内自由电子复合，形成负离子，这时池内的自由电子就明显减少，这种基流的变化经放大器放大后，在记录仪或数据处理机上记录下来。

3 主要技术数据放射源：63Ni（活度为3.7×108Bq）电极型式：圆筒对称电极离子室容积：约0.8ml最高使用温度：350℃敏感度：5×10-13g/ml（γ-666）线性范围：约103基流：大于1×10-9A基线漂移：在30min内，波动范围不超过0.2mV4 安装4.1 安装条件本ECD采用了63Ni 放射性同位素，仪器操作者应具有这方面的基本知识，方能安装操作。

载气通常使用氮气，它的纯度应高于99.999%，如果纯度不够，将使基流降低，噪声加大，稳定性变坏，线性范围变窄。

载气中的含氧和水量最好在1μl/L以下。

4.1.1 色谱柱的活化ECD是属于高灵敏度、选择性检测器，未经活化或活化不完全的色谱柱接入检测器是很危险的，轻者使噪声增加，灵敏度降低，严重污染会使基流很小，甚至没有基流。

另外ECD在选择色谱柱时，应尽量选用使用温度高的固定液，并且在满足分析要求的情况下，应使用较低的柱温，否则温度波动、载气流的波动都会引起固定液的蒸汽压的变化，造成基线噪声增加和基线的大幅度漂移。

It complies with IMO MSC.74(69) Annex 3, A.694, ITU-R M.1371-1 and DSC ITU-R M.825. It also complies with IEC 61993-2 (Type testing standard), IEC 60945 (EMC and environmental conditions).The FA-100 consists of VHF/GPS antennas, a transponder unit and several associated units.The transponder contains a VHF transmitter, two TDMA receivers on two parallel VHF channels, a DSC channel 70 receiver, interface, communication processor, LCD display, and internal GPS receiver. The internal 12-channel all-in-view GPS receiver with a system synchronization toeliminate clash among amultiple users.

The new RP radar plotting modules provide practically unlimited number of AIS targets together with ARPA symbols.Operational concept is common to all RP-modules. Place the cursor on an AIS target of interest and hit the AIS Data key, and the relevant data is visible on the data area below the ARPA data cell. If multiple AIS symbols mask the ARPA and radar picture, you can sleep the AIS targets.The triangle symbols get smaller for positive The AIS target symbols appear as defined by the SN/Circ.217 as follow: AIS COG/SOG vector changes its length with speed and adjustable in cycle time.ROT mark is viewable at the COG/SOG vector tip when a target ship is equipped with a Furuno GPS compass SC-60 or 120.The Automatic Identification System (AIS) wasoriginally developed to aid the Vessel Traffic Services (VTS) by use of VHF transponder working on Digital Selective Call (DSC) at VHF Channel 70 and is still in use along the UK coastal areas and others. Afterward the IMO developed a Universal AIS using the new sophisticated technology called Self-Organized Time Division Multiple Access (SOTDMA) based on a VHF Data Link (VDL).This system is synchronized with GPS time to avoid conflict among multiple users (IMO minimum 2000reports per minute and IEC requires 4500 reports on two channels).The system operates in 3 modes - autonomous (continuous operation in all areas), assigned (data transmission interval remotely controlled by authority in traffic monitoring service) and polled (in response to interrogation from a ship or authority). The VHF channels 87B and 88B are commonly used and in addition there are local AIS frequencies. Theshipborne AIS transponders exchange various data as specified by the IMO and ITU on either frequency automatically set up by the frequency management telecommand received by the DSC receiver on ship.VHF transmit power is also set up for 12.5 W or 2 Wautomatically.System OverviewSystem OverviewAll ships broadcast Static and Dynamic information (autonomous and continuous mode).If OS wants to know information about ship 1, OS shall send an interrogation in polling mode;then ship 1 will transmit her response on the same VHF channel without operator intervention.s Static DataMMSI (Maritime Mobile Service Identity)IMO number (Where available)Call sign & name Length and beam Type of shipLocation of position-fixing antenna on the ships Dynamic dataShip’s position with accuracy indication and integrity status UTCCourse over ground (COG)Speed over ground (SOG)HeadingNavigation status (manual input)Rate of turn (where available)Update rates Dependent on speed and course alternation (2 s – 3 min)s Voyage related data Ship’s draughtHazardous cargo (type)Destination and ETA (at masters discretion)Implementation schedule(MSC.73 adopted 5 December 2001 and Amendments adopted 13 December 2002 by the Conference of Contracting Governments to the SOLAS 1974)1New building on and after 1 July 2002: .1All ships of ≥300 GT on int'l voyages.2Cargo ships ≥500 GT not on int'l voyages .3Passenger ships irrespective of size on all voyages 2Ships on int'l voyages constructed before 1 July 2002.1Passenger ships: before 1 July 2003.2Tankers: before first survey of safety equipment after 1 July 2003.3Ships, other than passenger and tankers, ≥50,000GT: before 1 July 2004.4Ships, other than passenger and tankers, ≥300GT but <50,000 GT: before first survey of safety equipment after 1 July 2004 or before 31December 2004, whichever occurs earlier 3Ships not on int'l voyages constructed before 1 July 2002: before 1 July 2008GENERALStandards I MO MSC.74(69) Annex 3,IEC 61993-2, ITU-R M.1371-1 Ship reporting capacity2000 reports per minute, 4500 reports per minute ontwo channelsTDMA TransmitterTX Frequency:156.025 MHz - 162.025 MHz,manual/automatic setting Transmitter Power: 2 W, 12.5 W manual/automaticselectionTDMA ReceiverRX Frequency:156.025 MHz-162.025 MHz by2 channelsRX1:Default CH87B (161.975 MHz),manual/automatic setting RX2:Default CH88B (162.025 MHz),manual/automatic setting Channel Spacing:25 kHz and 12.5 kHzDSC ReceiverRX Frequency: CH70 (156.525 MHz)Internal GPS ReceiverType:GN-79N5A-N, 12 CHAccuracy:10 m (GPS), 5 m (DGPS withoptional beacon receiver)UTC Synchronization Jitter (time between slot start andtransmitter on): ±100 µsExternal GPS ReceiverGP-80, GP-500 MK 2, SC-60/SC-120 (if approved by Administrations)Navigational dataCOG/SOG, ROT, POS, Heading from external sources DisplayText (meets IMO minimum requirements) scrolled on LCD screen 95 x 65 mmGraphical (optional) on Radar model FR-15x5 MK 3Series (with RP-180 module), FR-21x5 Series (withRP-250 module), FAR-28x5 Series (with RP-340module)Existing radars can be upgraded for AIS target viewwith one of these RP cards.INTERFACEInput ABM, ACA, ACK, AIR, BBM, DTM, GBS,GGA, GLL, GNS, HDT, OSD, SSD, RMC,ROT, VBW, VSD, VTG, LRF, LRIOutput ABK, VDO, VDM, ACA, ACS, ALR, LRF,LR1, LR2, LR3, TXTPOWER SUPPLY12-24 VDC, 7-3.5 A, 115/230 VAC with rectifier ENVIRONMENTIEC 60945 for EMC, Vibration, TemperatureEQUIPMENT LISTStandard1.Transponder Unit 1 unit2.GPS Antenna Unit GSC-001 orGPS/VHF Combined Antenna Unit GVA-100with Distribution Box DB-1 1 unit3.Junction Box CB-100 1 unit4.Installation Materials 1 set Optional1.VHF Antenna Unit 150M-W2VN with bracket2.GPS/VHF Combined and GPS Antenna Cable kitTNC-PS-3D-15 (15 m), CP20-01700 (30 m),CP20-01710 (50 m)3.Antenna Base No. 13-QA330, No. 13-QA310,No. 13-RC51604.Software for PC (under developing)5.DGPS Beacon Receiver GR-806.Pilot plug7.Flush Mount Kit A and B8.Power Supply Unit PR-240Note: IMO requires the AIS operates on ship's mains (115/230 VAC) and alternative source, then a PR-240 is required.

USP-88-生物实验

88BIOLOGICAL REACTIVITY TESTS, IN VIVOThe following tests are designed to determine the biological response of animals to elastomerics, plastics, and other polymeric material with direct or indirect patient contact, or by the injection of specific extracts prepared from the material under test. It is essential to make available the specific surface area for extraction. When the surface area of the specimen cannot be determined, use 0.1 g of elastomer or 0.2 g of plastic or other material for every mL of extraction fluid. Also, it is essential to exercise care in the preparation of the materials to be injected or instilled to prevent contamination with microorganisms and other foreign matter. Three tests are described. The Systemic Injection Test and the Intracutaneous Test are used for elastomeric materials, especially to elastomeric closures for which the appropriate Biological Reactivity Tests, In Vitro 87 have indicated significant biological reactivity. These two tests are used for plastics and other polymers, in addition to a third test, the Implantation Test, to test the suitability of these materials intended for use in fabricating containers and accessories thereto, for use in parenteral preparations, and for use in medical devices, implants, and other systems.These three tests are applied to materials or medical devices, if there is a need for classification of plastics and other polymers based on in vivo biological reactivity testing.For the purpose of this chapter, these definitions apply: the Sample is the specimen under test or an extract prepared from such a specimen. A Blank consists of the same quantity of the same extracting medium that is used for the extraction of the specimen under test, treated in the same manner as the extracting medium containing the specimen under test. A Negative Control1is a specimen that gives no reaction under the conditions of the test.CLASSIFICATION OF PLASTICSSix Plastic Classes are defined (see Table 1). This classification is based on responses to a series of in vivo tests for which extracts, materials, and routes of administration are specified. These tests are directly related to the intended end-use of the plastic articles. The choice of extractants is representative of the vehicles in preparations with which the plastics are likely to be in contact. The Table 1 classification facilitates communication among suppliers, users, and manufacturers of plastics by summarizing the tests to be performed for containers for injections and medical devices if a need for classification exists.Table 1.

Therefore, the class designation of a plastic must be accompanied by an indication of the temperature of extraction (e.g., IV-121, which represents a class IV plastic extracted at 121, or I-50, which represents a class I plastic extracted at 50).Plastics may be classified as USP Plastic Classes I–VI only on the basis of the response criteria prescribed in Table 1.This classification does not apply to plastics that are intended for use as containers for oral or topical products, or that may be used as an integral part of a drug formulation. Table 1 does not apply to natural elastomers, which are to be tested in Sodium Chloride Injection and vegetable oils only.The Systemic Injection Test and the Intracutaneous Test are designed to determine the systemic and local, respectively, biological responses of animals to plastics and other polymers by the single-dose injection of specific extracts prepared from a Sample. The Implantation Test is designed to evaluate the reaction of living tissue to the plastic and other polymers by the implantation of the Sample itself into animal tissue. The proper preparation and placement of the specimens under aseptic conditions are important in the conduct of the Implantation Test.These tests are designed for application to plastics and other polymers in the condition in which they are used. If the material is to be exposed to any cleansing or sterilization process prior to its end-use, then the tests are to be conducted on a Sample prepared from a specimen preconditioned by the same processing.Factors such as material composition, processing and cleaning procedures, contacting media, inks, adhesives, absorption, adsorption and permeability of preservatives, and conditions of storage may also affect the suitability of a material for a specific use. Evaluation of such factors should be made by appropriate additional specific tests to determine the suitability of a material for its intended use.USP R EFERENCE S TANDARDS 11—USP High-Density Polyethylene RS.Extracting Media—SODIUM CHLORIDE INJECTION (see monograph). Use Sodium Chloride Injection containing 0.9% of NaCl.1 IN 20 SOLUTION OF ALCOHOL IN SODIUM CHLORIDE INJECTION.POLYETHYLENE GLYCOL 400 (see monograph).VEGETABLE OIL—Use freshly refined Sesame Oil (see monograph) or Cottonseed Oil (see monograph) or other suitable vegetable oils.DRUG PRODUCT VEHICLE (where applicable).WATER FOR INJECTION (see monograph).NOTE—The Sesame Oil or Cottonseed Oil or other suitable vegetable oil meets the following additional requirements. Obtain, if possible, freshly refined oil. Use three properly prepared animals, and inject the oil intracutaneously in a dose of 0.2 mL into each of 10 sites per animal, and observe the animals at 24, 48, and 72 h following injection. Rate the observations at each site on the numerical scale indicated in Table 2. For the 3 rabbits or guinea pigs (30 or 18 injection sites), at any observation time, the average response for erythema is not greater than 0.5 and for edema is not greater than 1.0, and no site shows atissue reaction larger than 10 mm in overall diameter. The residue of oil at the injection site should not be misinterpreted as edema. Edematous tissue blanches when gentle pressure is applied.Table 2.

J Pharmacol Exp Ther 1944;82:377–390.b Excludes noninflammatory (mechanical) edema from the blank or extraction fluid.Apparatus— The apparatus for the tests includes the following. AUTOCLAVE— Use an autoclave capable of maintaining a temperature of 121 ± 2.0, equipped with a thermometer, a pressure gauge, a vent cock, a rack adequate to accommodate the test containers above the water level, and a water cooling system that will allow for cooling of the test containers to about, but not below, 20 immediately following the heating cycle.OVEN— Use an oven, preferably a forced-circulation model, that will maintain operating temperatures of 50 or 70within ±2.EXTRACTION CONTAINERS— Use only containers, such as ampuls or screw-cap culture test tubes, of Type I glass. If used, culture test tubes are closed with screw caps having suitable elastomeric liners. The exposed surface of the elastomeric liner is completely protected with an inert solid disk 0.05–0.075 mm in thickness. A suitable disk may be fabricated from a polytef resin.Preparation of Apparatus—Cleanse all glassware thoroughly with chromic acid cleansing mixture, or if necessary, with hot nitric acid, followed by prolonged rinsing with water. Clean cutting utensils by an appropriate method (e.g., successive cleaning with acetone and methylene chloride) prior to use in subdividing a specimen. Clean all other equipment by thorough scrubbing with a suitable detergent and prolonged rinsing with water.Render containers and equipment used for extraction, and in transfer and administration of test material, sterile and dry by a suitable process. [NOTE—If ethylene oxide is used as the sterilizing agent, allow adequate time for complete degassing. ]Procedure—PREPARATION OF SAMPLE— Both the Systemic Injection Test and the Intracutaneous Test may be performed using the same extract, if desired, or separate extracts may be made for each test. Select and subdivide into portions a Sample of the size indicated in Table 3. Remove particulate matter, such as lint and free particles, by treating each subdivided Sample or Negative Control as follows. Place the Sample into a clean, glass-stoppered, 100-mL graduated cylinder of Type I glass, and add about 70 mL of Water for Injection. Agitate for about 30 s, and drain off the water. Repeat this step, and dry those pieces prepared for the extraction with Vegetable Oil in an oven at a temperature not exceeding 50. [NOTE—Donot clean the Sample with a dry or wet cloth or by rinsing or washing with an organic solvent, surfactant, etc. ]Table 3.

Repeat these directions for each extracting medium required for testing. Also, prepare one 20-mL blank of each medium for parallel injections and comparisons. Extract by heating in an autoclave at 121 for 60 min, in an oven at 70 for 24 h, or at 50 for 72 h. Allow adequate time for the liquid within the container to reach the extraction temperature. [NOTE—The extraction conditions should not in any instance cause physical changes such as fusion or melting of the Sample pieces, which result in a decrease in the available surface area. A slight adherence of the pieces can be tolerated. Always add the cleaned pieces individually to the extracting medium.If culture tubes are used for autoclave extractions with Vegetable Oil, seal screw caps adequately with pressure-sensitive tape. ]Cool to about room temperature but not below 20, shake vigorously for several minutes, and decant each extract immediately, using aseptic precautions, into a dry, sterile vessel. Store the extracts at a temperature of 20–30, and do not use for tests after 24 h. Of importance are the contact of the extracting medium with the available surface area of the plastic and the time and temperature during extraction, the proper cooling, agitation, and decanting process, and the aseptic handling and storage of the extracts following extraction.SYSTEMIC INJECTION TESTThis test is designed to evaluate systemic responses to the extracts of materials under test following injection into mice. Alternate routes of injection may be used with justification.Test Animals— Use healthy, not previously used albino mice weighing 17–23 g. For each test group use only mice of the same source. Allow water and food, commonly used for laboratory animals and of known composition, ad libitum.Procedure—[NOTE—Agitate each extract vigorously prior to withdrawal of injection doses to ensure even distribution of the extracted matter. ] Inject each of the five mice in a test group with the Sample or the Blank as outlined in Table 4, except to dilute each g of the extract of the Sample prepared with Polyethylene Glycol 400, and the corresponding Blank, with 4.1 volumes of Sodium Chloride Injection to obtain a solution having a concentration of about 200 mg of polyethylene glycol per mL.Table 4.

If during the observation period none of the animals treated with the extract of the Sample shows a significantly greater biological reactivity than the animals treated with the Blank, the Sample meets the requirements of this test. If two or more mice die, or if abnormal behavior such as convulsions or prostration occurs in two or more mice, or if a body weight loss greater than 2 g occurs in three or more mice, the Sample does not meet the requirements of the test. If any animals treated with the Sample show only slight signs of biological reactivity, and not more than one animal shows gross symptoms of biological reactivity or dies, repeat the test using groups of 10 mice. On the repeat test, all 10 animals treated with the Sample show no significant biological reactivity above the Blank animals during the observation period.INTRACUTANEOUS TESTThis test is designed to evaluate local responses to the extracts of materials under test following intracutaneous injection into rabbits or guinea pigs.Test Animals— Select healthy, rabbits or guinea pigs with fur that can be clipped closely and skin that is free from mechanical irritation or trauma. In handling the animals, avoid touching the injection sites duringobservation periods, except to discriminate between edema and an oil residue.Procedure—[NOTE—Agitate each extract vigorously prior to withdrawal of injection doses to ensure even distribution of the extracted matter. ] On the day of the test, closely clip the fur on the animal's back on both sides of the spinal column over a sufficiently large test area. Avoid mechanical irritation and trauma. Remove loose hair by means of vacuum. If necessary, swab the skin lightly with diluted alcohol, and dry the skin prior to injection. More than one extract from a given material can be used per rabbit or guinea pig, if it is determined that the test results will not be affected. For each Sample use two animals and inject each intracutaneously, using one side of the animal for the Sample and the other side for the Blank, as outlined in Table 5. [NOTE—Dilute each g of the extract of the Sample prepared with Polyethylene Glycol 400, and the corresponding Blank, with 7.4 volumes of Sodium Chloride Injection to obtain a solution having a concentration of about 120 mg of polyethylene glycol per mL. ]Table 5. Intracutaneous TestExtract or Blank Number of Sites(per animal)Dose(µL per site)Sample5200Blank5200Examine injection sites for evidence of any tissue reaction such as erythema, edema, and necrosis. Swab the skin lightly, if necessary, with diluted alcohol to facilitate reading of injection sites. Observe all animals at 24, 48, and 72 h after injection. Rate the observations on a numerical scale for the extract of the Sample and for the Blank, using Table 2. Reclip the fur as necessary during the observation period. The average erythema and edema scores for Sample and Blank sites are determined at every scoring interval (24, 48, and 72 h) for each rabbit or guinea pig. After the 72-hour scoring, all erythema scores plus edema scores are totalled separately for each Sample and Blank. Divide each ofthe totals by 12 (2 animals × 3 scoring periods × 2 scoring categories) to determine the overall mean score for each Sample versus each corresponding Blank. The requirements of the test are met if the difference between the Sample and the Blank mean score is 1.0 or less. If at any observation period the average reaction to the Sample is questionably greater than the average reaction to the Blank, repeat the test using three additional rabbits or guinea pigs. The requirements of the test are met if the difference between the Sample and the Blank mean score is 1.0 or less.IMPLANTATION TESTThe implantation test is designed for the evaluation of plastic materials and other polymeric materials in direct contact with living tissue. Of importance are the proper preparation of the implant strips and their proper implantation under aseptic conditions. The intramuscular implantation test requires healthy adult New Zealand rabbits. The test specimens are placed into needles as the delivery system for implantation. Although most materials lend themselves readily to this method, there are a number of materials that are unsuitable for intramuscular implantation. For materials with physical characteristics unsuitable for routine intramuscular implantation, the subcutaneous rat implantation model is a viable alternative.Intramuscular Implantation in RabbitsPrepare for implantation 8 strips of the Sample and 4 strips of USP High-Density Polyethylene RS. Each strip should measure not less than 10 × 1 mm. The edges of the strips should be as smooth as possible to avoid additional mechanical trauma upon implantation. Strips of the specified minimum size are implanted by means of a hypodermic needle (15–19 gauge) with intravenous point and a sterile trocar. Use either presterilizedneedles into which the sterile plastic strips are aseptically inserted, or insert each clean strip into a needle, the cannula and hub of which are protected with an appropriate cover, and then subjected to the appropriate sterilization procedure. [NOTE—Allow for proper degassing if agents such as ethylene oxide are used. ]Test Animals— Select healthy, adult rabbits weighing not less than 2.5 kg, and with paravertebral muscles that are sufficiently large in size to allow for implantation of the test strips. Do not use any muscular tissue other than the paravertebral site. The animals must be anesthetized with a commonly used anesthetic agent to a degree deep enough to prevent muscular movements, such as twitching. See the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) guidelines. Procedure— Perform the test in a clean area. On the day of the test or up to 20 h before testing, clip the fur of the animals on both sides of the spinal column. Remove loose hair by means of vacuum. Swab the skin lightly with diluted alcohol, and dry the skin prior to injection. Implant four strips of the Sample into the paravertebral muscle on one side of the spine of each of two rabbits, 2.5–5 cm from the midline and parallel to the spinal column, and about 2.5 cm apart from each other. In a similar fashion implant two strips of USP High-Density Polyethylene RS in the opposite muscle of each animal. Insert a sterile stylet into the needle to hold the implant strip in the tissue while withdrawing the needle. If excessive bleeding is observed after implantation of a strip, place a duplicate strip at another site.Keep the animals for a period of not less than 120 h, and sacrifice them at the end of the observation period by administering an overdose of an anesthetic agent or other suitable agents. Allow sufficient time to elapse for the tissue to be cut without bleeding. Examine macroscopically the area of the tissue surrounding the center portion of each implant strip.Use a magnifying lens and auxiliary light source. Observe the Sample and Control implant sites for hemorrhage, necrosis, discolorations, and infections, and record the observations. Measure encapsulation, if present, by recording the width of the capsule (from the periphery of the space occupied by the implant Control or Sample to the periphery of the capsule) rounded to the nearest 0.1 mm. Score encapsulation according to Table 6.Table 6. Evaluation of Encapsulation in the Implantation TestCapsule Width ScoreNone 0Up to 0.5 mm10.6–1.0 mm21.1–2.0 mm 3Greater than 2.0 mm4Calculate the differences between average scores for the Sample and Control sites. The requirements of the test are met if the difference does not exceed 1.0, or if the difference between the Sample and Control mean scores for more than one of the four implant sites does not exceed 1 for any implanted animal.Subcutaneous Implantation in RatsPrepare for implantation 10 sample specimens and 10 control specimens. The size and shape of the control specimens shall be as similar to that of the test specimens as practically possible. For example, specimens made of sheeting material shall be 10–12 mm in diameter and from 0.3–1 mm in thickness. The edges of the specimens should be as smooth as possible to avoid additional mechanical trauma upon implantation.Test Animals—Select healthy albino rats weighing 225–350 g at the time of implantation.Procedure— Perform the test in a clean area. Anesthetize (see AAALAC guidelines) the animal until a surgical plane is achieved. Clip the fur of the animals on both sides of the spinal column. Remove loose hair bymeans of vacuum. Clean the clipped area with povidone–iodine solution. Using aseptic technique, make two midline incisions (approximately 1.0 cm long) through the skin at the cranial and caudal regions on the dorsal surface. Using blunt dissection, separate the fascia connecting skin to muscle to form a pocket underneath the skin lateral to each side of the incision (base of pocket approximately 20 mm from the line of implant). Insert a sterile sample into each pocket, and close the incision with wound clips or sutures. Implant two test samples and two control samples in each of five rats. Keep the animals for a period of at least seven days, and sacrifice them at the end of the observation period by CO2induced hypoxia or administering an overdose of an anesthetic agent. Allow sufficient time to elapse for the tissue to be cut without bleeding. Cut the skin (dorsal surface) longitudinally and lay back. Carefully examine macroscopically the area of the tissue surrounding the implant. Cut the sample in half and remove for close examination of the tissue in direct contact with the sample. Use a magnifying lens and auxiliary light source, if appropriate. Observe the Sample and Control implant sites for hemorrhage, necrosis, discolorations, and infections, and record the observations. Measure encapsulation, if present, by recording the width of the capsule (from the periphery of the space occupied by the implant Control or Sample to the periphery of the capsule) rounded to the nearest 0.1 mm. Score encapsulation according to Table 6. Calculate the differences between average scores for the Sample and Control sites. The requirements of the test are met if the difference does not exceed 1.0.SAFETY TESTS—BIOLOGICALSThe safety test set forth here is intended to detect in an article any unexpected, unacceptable biological reactivity. This in vivo test is provided for the safety assessment of biotechnology-derived products.Safety TestSelect five healthy mice not previously used for testing, weighing 17–23 g, unless otherwise directed in the individual monograph or elsewhere in this chapter, and maintained on an adequate balanced diet. Prepare a test solution as directed in the individual monograph. Unless otherwise directed in the individual monograph or elsewhere in this chapter, inject a dose of 0.5 mL of the test solution into each of the mice, using a 26-gauge needle of suitable length, or of the length specified below as applicable. Observe the animals over the 48 h following the injection. If, at the end of 48 h, all of the animals survive and not more than one of the animals shows outward symptoms of a reaction not normally expected of the level of toxicity related to the article, the requirements of this test are met. If one or more animals die or if more than one of the animals shows signs of abnormal or untoward toxicity of the article under test, repeat the test using at least another 10 mice similar to those used in the initial test, but weighing 20 ± 1 g. In either case, if all of the animals survive for 48 h and show no symptoms of a reaction indicative of an abnormal or undue level of toxicity of the article, the requirements of the test are met. Body weights of mice before and at the end of the test should be obtained to detect any untoward effects. Animals that show signs of toxicity should be grossly necropsied and subjected to histopathology if necessary.For biologics, perform the test according to the procedures prescribed in the Code of Federal Regulations, Section 610.11.1 USP High-Density Polyethylene RS.contacting USP.Topic/Question Contact Expert CommitteeGeneral Chapter Desmond G.

在线富集毛细管电泳法与荧光法测定四种兽药残留的开题报告

在线富集毛细管电泳法与荧光法测定四种兽药残留的开题报告一、研究目的本研究旨在建立一种可同时测定四种兽药残留的在线富集毛细管电泳法（online concentration capillary electrophoresis，ocCE）和荧光法测定方法。

二、研究背景兽药是为了治疗、预防或控制动物疾病而使用的药品。

但如果动物体内药物残留量过高，又将对人体健康带来威胁。

因此，对动物产品中的兽药残留进行监测和控制就显得尤为重要。

传统的兽药残留检测方法包括高效液相色谱法、气相色谱法等，这些方法在分离、测定精度等方面具有很高的水平。

然而这些方法也存在一些不足，如分析速度较慢、需大量的实验室设备和抽提物等。

为解决这些问题，毛细管电泳作为一种高效和灵敏的分析技术，被广泛应用于兽药残留检测领域。

而在线富集毛细管电泳法则是通过在线实现样品前富集方式提高检测灵敏度的方法，应用范围更加广泛。

三、研究内容与方法1. 研究内容本研究将首先使用在线富集毛细管电泳法对四种兽药进行分离和测定，并比较在线富集毛细管电泳法与常规毛细管电泳法的检测效果。

随后，采用荧光探针（如纳米金荧光标记试剂）将在线富集毛细管电泳法与荧光探针结合，建立一种同时测定四种兽药残留的荧光法测定方法，并对比两种方法的测定效果。

2. 研究方法（1）在线富集毛细管电泳法在线富集毛细管电泳法采用溶胶迁移模式，首先对样品进行在线富集，然后在毛细管中通过电场力将富集的物质铺展成带状，从而实现样品的分离和检测。

在线富集毛细管电泳法的操作流程包括：①在毛细管管道中输入胶体缓冲液；②在在线富集器中输入检测物质的样品溶液，通过注入电压驱动溶液进入负载预处理柱，对样品进行富集和前处理；③通过极化电压，对样品进行分离和检测。

（2）荧光法测定方法通过将纳米金荧光探针与目标分子结合制成药物检测体系，并进一步进行在线富集毛细管电泳分离和检测。

荧光法测定方法的流程包括：①制备药物检测体系：将纳米金荧光探针与目标兽药结合制成药物检测体系；②在线富集毛细管电泳分离：将药物检测体系输入在线富集毛细管电泳仪进行在线富集毛细管电泳分离；③检测：通过荧光探测器检测药物检测体系中的荧光强度，获得对目标兽药的定量结果。

高效液相色谱法测定食用菌中福美双残留量

高效液相色谱法测定食用菌中福美双残留量摘要：建立食用菌中福美双残留量的高效液相色谱(HPLC)检测方法。

新鲜食用菌子实体样品粉碎后经二氯甲烷超声（53 Hz）提取20 min，离心（3320 g、5 min）, 二氯甲烷经氮气吹干，甲醇定容后用HPLC测定。

以等体积甲醇和0.1%甲酸水溶液为流动相，1 mL/min等度洗脱，在0.05～10 μg/mL范围内，福美双的峰面积与其浓度呈线性相关，R≥0.999，方法检出限为0.02 mg/kg，添加回收率为79.4%～90.2%，变异系数为1.15% ～7.51%%。

关键词：福美双；食用菌；子实体; 高效液相色谱福美双（Thiram）是一种脊椎动物趋避剂、杀菌剂,对葡萄孢菌、黑星病菌、疫霉菌等都有活性，在我国是在蔬菜和食用菌中登记使用的农药。

福美双防治食用菌病害效果显著，因此被广大菇农使用［1］。

福美双对水生物和野生鸟类及哺乳动物存在危险，因此其残留危害不容忽视。

对于福美双的测定，主要有液相色谱法［2-7］，气相色谱法［8］，紫外分光光度法［9］。

气相色谱法的分析原理是将福美双经过酸分解产生二硫化碳，然后通过测定二硫化碳来计算福美双的含量，该测定方法的检出限能达到0.01 mg/kg ，但是有机硫杀菌剂，例如代森锌、代森锰、福美锌等均可被无机酸分解生成二硫化碳，无法区分实际使用的是哪种农药; 紫外分光光度法，其仪器测定的灵敏度和定性的准确度较差,较难满足目前对于农产品检测的苛刻要求; 本研究旨在建立食用菌中福美双残留量的高效液相色谱测定方法，给相关部门对于福美双残留量的监测提供参考。
