The potential will then scan back. The following diagram shows the potential waveform applied as the function of time. The current is recorded as the function of potential.The following are the experimental parameters, their range and descriptions:Parameters Range Description Init E (V)-10 - +10Initial potential High E (V)-10 - +10High limit of potential scan Low E (V)-10 - +10Low limit of potential scan Init P/NPositive or Negative Initial scan direction Scan Rate (V/s)1e-6 - 20000Potential scan rate Sweep Segments1 - 1000000Sweep segments, each segments is half cycle Sample Interval (V)1e-6 - 0.064Data sampling interval Quiet Time (sec)0 - 100000Quiescent time before potential scan Sensitivity (A/V)1e-12 - 0.1Sensitivity scale Auto SensCheck or Uncheck Automatic sensitivity switching during run Scan Complete CyclesCheck or Uncheck Scan complete cycles Auxiliary SignalRecordingCheck or Uncheck Simultaneously external signal recording when the scan rate is less than 0.25V/sNotes:P o t e n t i a l (V )Init ETime (s)High EScan Rate (V/s)Segment 1Segment 2Segment 3Low E________________________________________________________________________1.High E and Low E should be at least 0.01 V apart.2.If unreasonable High E and Low E are entered, the system will automatically readjust them.3.Depending on the Init E, High E and Low E value, the system will automatically readjust initial scan direction.4.The maximum potential scan range is 13.1V.5.The potential increment is 0.1 mV if the scan rate is below 500 V/s. The potential increment is 1 mV at the scan rate of 5000 V/s, and 4 mV at 20000 V/s.6.The sample interval can be 1 mV When the scan rate is below 1000 V/s. The sample interval is 2 mV at the scan rate of 2000 V/s, 5 mV at 5000 V/s, and 20 mV at 20000 V/s. If the scan rate is high, the data sampling interval will be automatically increased.7.When large number of sweep segments are involved, the data sampling interval will be automatically increased up to 0.02V. If the scan rate is higher than 0.5V/s, the number of sweep segments will be limited by the memory size (64000 points). If the scan rate is below 0.5V/s, the maximum data length set by the System command will take effect. When the scan rate is low, the specified sweep segments will be executed, but only limited number of segments will be stored. Large sweep segments might be useful for conditioning of electrodes.8.When scan rate is below 0.01 V/s, the sensitivity scale during run can be automatically switched according to the current level. When it is activated, the sensitivity selection will have no effect on the measurement. However, the automatic sensitivity switching range will be from 1e-8 - 0.1 A/V, instead of 1e-12 - 0.1 A/V. The Picoamp Booster will not work either. In order to select higher sensitivities, automatic sensitivity switching option needs to be disabled.9.Scan Complete Cycles will only work for Sweep Segments at 3, 5, 7, 9, (odd numbers) and if Initial E is different from High E and Low E. When it works, the last segment will stop at Initial E instead of High E or Low E.10.If the scan rate is lower than 0.25V/s, it is possible to record external voltage signal (such s spectroscopic signal) simultaneously with the voltammogram. Use the 9-pin D-connector on the real panel for signal input. Check the User's Manual for the pin-out and signal level requirements.________________________________________________________________________Parameters for Linear Sweep VoltammetryIn Linear Sweep Voltammetry (LSV), potential is scanned from Init E toward Final E.The following diagram shows the potential waveform applied as the function of time.

Use the 9-pin D-connector on the real panel for signal input. Check the User's Manual for the pin-out and signal level requirements.8. Linear polarization resistance plot can be obtained by the Special Plots command under the Graphics menu.Parameters for Tafel PlotIn Tafel Plot (TAFEL), potential is scanned from Init E toward Final E. The potential may be scanned back. The following diagram shows the potential waveform applied as the function of time. The logarithm of current is recorded as the function of potential.The following are the experimental parameters, their range and descriptions:Parameters Range Description Init E (V)-10 - +10Initial potential Final E (V)-10 - +10Final potential Sweep Segments1 - 2Sweep segments, each segments is half cycle Hold Time at Final E (s)0 - 100000Potential hold time atfer 1st sweep segent Scan Rate (V/s)1e-6 - 0.1Potential scan rate Quiet Time (sec)0 - 100000Quiescent time before potential scan Sensitivity (A/V)1e-12 - 0.1Sensitivity scale Auto Sens Check orUncheck Automatic sensitivity switching during runNotes:1.Init E and Final E should be at least 0.01 V apart.2.Corrosion rate calculation can be obtained by Special Analysis command under the Analysis menu.P o t e n t i a l (V )Init ETime (s)Final EScan Rate (V/s)Segment 1Segment 2Hold TimeSystem CommandUse this command to set up the serial communication port, current polarity, potential axis and current axis.This command presents a System Setup dialog box:The following options allow you to set up your system:Communication PortSelect the communication port to link the PC to the instrument.Com Port SpeedSelect the communication port speed to link the PC to the instrument. Standard is guaranteed to work with any computer. Fast may or may not work with a particularcomputer. When Fast is chosen, the real time data transfer will be done at higher scan rate or shorter sample interval.Current PolarityYou can either select cathodic current as positive current or anodic current as positive current. You should set this before experiment, otherwise the experimental results (peaks and waves) will not be reported properly.________________________________________________________________________ Potential AxisYou can set positive potential axis either left or right. This is meaningful only for voltammetric or polarographic modes.Current AxisYou can set positive current axis either up or down.Line FrequencySet line frequency according to what is applied. This helps set default sample interval in certain techniques to reduce the interference from the line frequency.Windowsif you are using English Windows, please choose English. If you are using Chinese, Japanese, or Korean Windows, check Oriental. Oriental Windows shows slightly bigger letters than English Windows. The Technique selection field may be truncated if you select English Windows. Also oriental Windows does not support certain symbols. For instance, symbol "µ" will not be displayed properly. Choose oriental Windows will use "u" instead of "µ".Data LengthThe default data length is 128K. The longer the data length, the more computer resource will be used. It is recommended not to use long data length unless necessary. Using long data length will need large computer memory such as 256M, 512M RAM or more. It will also slow down the system and prohibit other programs to run.After you change the data length setting in the System Setup command, please exit the program and restart the program so that the data length can be set properly. Otherwise the program may crash.If the data is acquired and saved with long data length setting, but read back with shorter data length setting, the program may crash. Therefore once you used long data length setting, you should not set to shorter data length later. Please think carefully before you decide to increase the data length.Save retrieve data during runCheck this option will allow data to be saved on the hard drive during run. In case experiment does not complete due to external interference or interruption, misscommunication, partial data can be recovered. This is useful for very slow experiments.Hours of experimental data can be recovered.This option is not active by default. If you do not run very slow experiments, you can re-run the experiment if the experiment is interrupted by accident.To retrieve experimental data of last run, you should use Retrieve command under the File menu.Present Data Override WarningIf your experimental data is not saved before running a new experiment or opening an existing file on the disk, your unsaved data will be overridden. This option will allow system to issue a warning before the data is lost.Save Text File As WellNormally only binary data files is saved. Binary file contains more information (including experimental control information) but small in size. This option allows you to________________________________________________________________________ save text file as well whenever you save the binary data. This is useful for those who want toexport data to other software, such as spreadsheet software.Erase ADC Calibration CoefficientsThe analog-to-digital converter (ADC) calibration coefficients are stored in the instrument non-volatile memory. ADC calibration is carried out in CH Instruments before the instrument is shipped. You use this command only if you want to recalibrate the ADC. After you erase ADC calibration coefficients, you will see a prompt of ADC calibration when you run next hardware test or experiment.________________________________________________________________________Hardware Test CommandUse this command to test the system hardware. The system will test digital and analog circuitry.After the test, the system will display the Hardware Test Results dialog box:Digital Circuitry TestThe software version and the last revision date for the Flash ROM is shown.Potential and current offset testIf test is failed, the error message will be given.Sensitivity scale testIf test is failed, the error message will be given. Most times the error is related to leakage current.Gain testThere are 3 gain stages. If test is failed, the error message will be given.Analog Test SummaryThe test results of analog circuitry are summarized. A message of “Analog circuitry test OK.” will appear if no error is detected, otherwise an error message will appear. In case there is error and the cause is due to the analog-to-digital converters, it will also be reported.If you see analog test error, please repeat the test several times and see if the error is consistent. Record the error message and contact the factory for servicing._____________________________________________________________________________________Open Circuit Potential CommandUse this command to measure the open circuit potential.The open circuit potential is the potential between the working electrode and reference electrode while no current flows through the cell. This is an important parameter. It tells you what is the initial state before you start experiment. You can then figure out if the compound under study is oxidizable or reducible.After the measurement, the system will display the open circuit potential value through the Open Circuit Potential dialog box. Click OK to close the dialog box after you read it._____________________________________________________________________________________iR Compensation CommandUse this command to test the solution resistance and the cell time constant, as well as to enable or disable automatic or manual iR compensation.This command presents an iR Compensation dialog box:The following options allow you to set iR compensation parameters:iR Comp Test ResultsIf you click the iR Test button, the system will engage solution resistance and cell time constant test. The result will be reported here.After that the system will test the stability by gradually increase the compensation level until the desired compensation level is reached or if the system is no longer stable. The actually allowed compensation level and the uncompensated resistance will be displayed.The uncompensated resistance is calculated from the measured resistance and the allowed compensation level.Please note that the maximum allowed resistance compensation may also be limited to the feedback resistor of the i/E converter.iR Comp TestBefore start iR compensation test, you should check the test parameters.Test E is the test potential where no electrochemical reaction will occur. When the system is doing test, it applies a potential step around the test potential. The test result is good only if the electrochemical cell can be equivalent to a solution resistance in series witha double layer capacitor. The range of Test E is -10V - +10V.You may adjust the potential step amplitude. The larger the amplitude, the higher the signal-to-noise ratio. However, too large amplitude may cause faradaic current to flow. A step amplitude of 0.05V is recommended. The range of Step Amplitude is 0.01 - 0.25 V._____________________________________________________________________________________ The compensation level is the percentage of resistance you want to compensate based on the measured solution resistance. The range of this parameter is 0 - 200%. The default value is 100%.Overshoot level is the criterion of the stability test. As the amount of positive feedback increases, the system might become unstable. Before the potentiostat start to oscillate, the overshoot in current response to the potential pulse will appear. The higher the allowedovershoot level, the higher the possible compensation level, but the worse the systemstability. The range of this parameter is 0 - 100%. The default level is 2%.If you click the iR Test button, the system will engage solution resistance and stability test. The result will be reported in the iR Comp Test Results Box.For more details about the iR compensation, please see “Intelligent, Automatic Compensation of Solution Resistance”, P. He, and L. R. Faulkner, Anal. Chem., 58, 517-523 (1986).iR Compensation for Next RunWhen this box is checked, the iR compensation for next run is enabled. You may not be able to enable iR compensation if the automatic compensation is set and the iR compensation test has not been conducted or the sensitivity scale has been altered. This option can also be turned on or off from Run Status command under Control menu.iR Comp EnableIf the option "Once" is chosen, the iR compensation will only be applied to next run and then disabled. If you want the same compensation conditions to be applied to the consecutive runs, choose "Always" option. Click the proper radio button to select the option.iR Comp ModeYou can choose automatic iR compensation or manual iR compensation. The automatic iR compensation will be based on the iR compensation test results. You can also choose manual iR compensation by entering the resistance value you want to compensate. Click the proper radio button to select the option.Manual Compensation ResistanceIf you select manual iR compensation, you should enter the resistance value that you want system to compensate. Be careful about the compensation level. If the compensation level is close or exceeds the actual solution resistance, the potentiostat will oscillate. Please also notice that the maximum allowed resistance compensation may be limited to thefeedback resistor of the i/E converter.This parameter has no effect if automatic iR compensation is selected.This command has a toolbar button:。

Autolab电化学工作站仪器的基本操作步骤

Autolab 电化学工作站使用说明1、开机前,检查电化学工作站与电脑的USB接线连接是否正常,保持正确连接。

2、接通电化学工作站主电源,按动电化学工作站前操作面板电源按钮Power键,即打开工作站。

3、启动电脑,并进入Windows操作系统。

4、在启动电脑的同时,电脑会自动检测与电化学工作站的连接情况以及电化学工作站内部设备是否运作正常。

自检完毕后,位于电脑屏幕右下角任务栏处的Autolab之Interface小图标正常显示,可进行下一步操作。

5、进行电化学方法测试前,首先将电化学工作站测量插头(分别是工作电极WE,反馈电极SE,辅助电极CE,参比电极RE)与电解池正确连接,注意电极的正负。

以经典的三电极电解槽为例,其中阴极为测量电极(即工作电解),接线方法为:WE与SE串连接后并与阴极连接,RE与参比电极连接,CE与辅助电极即阳极连接。

6、若进行基本电化学方法测试,点击Autolab之GPES图标,出现该测量界面,进行基本电化学测试,选择相应的Procedure/Method,输入相应的参数,确定参数输入无误后,点击Start按钮,进行测试。

测试完毕后,需要手动保存数据,以免数据丢失,特别需要注意的是保存路径中不能出现中文,否则不能保存数据,也不能打开数据。

7、若进行交流阻抗测试,点击Autolab之FRA图标,出现该测量界面,可行进行交流阻抗测试,选择相应的Procedure/Method,输入相应的参数,确定参数输入无误后,点击Start按钮,进行测试。

测试完毕后,需要手动保存数据,操作同一。

8、在测试间隙待机状态下,四根电极接线不宜空置,需要与实际体系连接,或插回Dummy Cell中,防止短路。

9、测试结束后,关闭电化学工作站的基本操作为:首先关闭软件操作界面,退出软件后,关闭电化学工作站前操作面板的电源按钮Power键,即关闭电化学工作站,最后切断电源。
