General Instructions for Care and UseContents of Package1 ZIC ®-c HILIC HPLC Column 1 Certificate of Analysis 1 Use and Care InstructionIntroductionThe ZIC ®-c HILIC column has a phosphorycholine zwitterionic stationary phase covalently attached to porous silica. The permanent and hydrophilic zwitterion functionality makes the column suitable for HydrophilicInteraction Liquid Chromatography (HILIC). Weak electrostatic interactions between charged analytes and the neutral zwitterionic stationary phase results in a unique selectivity, and especially suitable for analytes that are poorly retained on reversed phase columns.The ZIC ®-c HILIC column can be used as a tool to change the selectivity or to improve peak resolution for polar and hydrophilic compounds such as carbohydrates, metabolites, acids and bases,organic and inorganic ions, metal complexes, amino acids, peptides, and protein digests.Column Hardware and Chemical CompatibilityThe capillary and microbore columns (0.3 - 1.0 mm ID) are made from stainless steel that has been internally glass lined, and has 10 - 32 UNF female fittings. The nano columns (0.1 mm ID) are made from poly(ether-ether ketone) [PEEK] sheeted fused silica tubing, and has 10 - 32 UNF female fittings. The frits have a porosity to retain 3 - 5 μm particles and are made from stainless steel.The ZIC ®-c HILIC column can be operated in the pH range 2 to 8, while strongly alkaline solutions and washing with sodium hydroxide should beavoided. The ZIC ®-c HILIC column can be heated and operated up to 70 °C.Cleaning and RegenerationIf the backpressure increases or a shift in selectivity is observed, use thefollowing recommended column wash procedure:30 column volumes of deionised water 30 column volumes of 0.5 M NaCl 30 column volumes of deionised waterAn initial washing with deionised water is used to remove organic solvent and polar impurities, followed by a flush with a 0.5 M sodium chloride solution. Finally remove the salt solution with sufficient water andequilibrate the column with 80 % (v/v) acetonitrile. On-line cleaning of the column can be accomplished by increasing the aqueous portion of the eluent close to 100 % while keeping a sufficient ion strength. Thisprocedure can be included at the end of a gradient run and is especially useful for routine applications with samples containing appreciable amounts of salts, such as urine and plasma.StorageThe column is delivered filled with 80 % (v/v) acetonitrile in ammonium acetate buffer (5 mM, pH 6.8) and that is also the recommended solvent for long term storage. Connect the end stop plugs when the column is removed from the system.Store columns as shipped:Acetonitrile / NH 4Ac 5 mM, pH 6.8; 80 : 20 (v/v)Dispose the column according to local authorities and regulations.Sample Solvent and Solvent StrengthSample solvents should consist of 60 - 100 % organic solvent, orinitialeluent composition. Water should be minimized. Weak HILIC solvents such as acetonitrile are favoured. It is recommended to have about 5 % water in the auto sampler wash solution. THF is normally a poor solvent for HILIC separations due to its strong hydrogen bonding ability.The relative solvent strength for HILIC is:Acetone<Acetonitrile<Isopropanol<Ethanol<Methanol<WaterMobile Phase ConsiderationsTo obtain reproducible results, maintain at least 3 % water in the mobile phase, in order to ensure sufficient hydration of the stationary phase particles.Suitable buffer systems for HILIC separations are formate and acetate, due to their excellent solubility even in very high concentrations of organic solvent. Avoid phosphate, and other low solubility buffers, to prevent precipitation on the column bed. A buffer concentration in the range 5 - 20 mM is recommended for most analytes, with an upper limit of 200 - 300 mM, depending on the solubility in the eluent. TFA and other ion pair reagents should be avoided, as they can interfere with the HILIC separa-tion mechanism, and suppress MS signals.Typical Elution ProtocolsIsocratic elution: 80 : 20 (v/v) acetonitrile / NH 4Ac, (5 - 20 mM) or other suitable buffer salt.Gradient elution:90 % to 40 % acetonitrile in 20 minutes (~2.5 %/min).Equilibrating the ColumnEquilibrate the column with 7 - 8 column volumes of initial mobile phase composition. Note that equilibration can be performed at higher flow rates to save time.Flow-rate and Injection VolumeNever exceed the maximum backpressure listed in the table below.The low viscosity of acetonitrile can enable very high flow-rates before maxpressure is reached. A suitable injection volume is about 1 % of the total column volume.Table: Flow-rate, backpressure and injection volumeColumn Injection Flow-Backpressure I.D.

液相色谱柱型号名称

液相色谱柱型号名称

液相色谱柱型号名称液相色谱技术是一种广泛应用于实验室和工业生产中的分离、纯化和分析技术。

而液相色谱柱作为液相色谱技术中不可或缺的组成部分,不同柱材质、柱型号都对色谱分离过程产生着重要影响。

以下是常用的液相色谱柱型号名称列表及其特点。

1. C18柱C18柱是一种经典的反相柱,在反相液相色谱分离中被广泛应用。

其最基本的特点是使用碳端基(-C18H37O)覆盖的硅胶基质,使得C18柱能够与极性化合物获得良好的相互作用,从而在分离过程中实现良好的分离效果。

C18柱的使用寿命长,稳定性高,适用于大多数样品分离。

2. C8柱C8柱与C18柱相似,但其具有更弱的相互作用能力。

因此,C8柱适用于一些更具极性的化合物分离,例如酚类、酮类和醛类等。

3. CN柱CN柱是一种极性的正相柱,在正相液相色谱分离中被广泛应用。

CN柱使用的是氰基覆盖的硅胶基质,能够与酸性和极性化合物获得良好的相互作用,对一些醇类、醛类和酮类等分子分离效果较好。

4. NH2柱NH2柱是一种偏极性正相柱,在正相液相色谱分离中应用较广。

NH2柱使用的是氨基覆盖的硅胶基质,能够与极性分子发生氢键作用。

NH2柱适用于如醇类、酮类、醛类、糖类等极性分子分离。

5. Phenyl柱Phenyl柱是一种反相柱,与C18柱相似,但其具有苯环的结构。

该结构赋予了Phenyl柱更强的π-π堆积相互作用,使得其中的芳香族化合物和芳基侧链能够得到更好的分离和识别。

6. C30柱C30柱是一种新型反相柱,在C18和C8柱之间。

C30柱的使用范围更广,能够处理更多的化学样品,例如脂肪酸、天然产物和药物等。

总之,不同的液相色谱柱型号具有不同的柱材质、柱层厚度、柱孔径、填充剂种类等特点,使用场合不同,选择的柱也不同。

选择合适的液相色谱柱型号来分离样品,将会获得更好的分离结果。

hplc色谱柱
HPLC(高效液相色谱)是一种常用的分离技术,广泛应用于
化学、生物、环境等领域。

而HPLC色谱柱是HPLC系统中
的核心组成部分,起着至关重要的作用。

HPLC色谱柱是一种用于分离和分析混合物的柱状装置。

它通
常由柱体、填料和保护层组成。

柱体是色谱柱的主体部分,填料则是用于分离混合物的介质,而保护层则用于保护填料和延长色谱柱的使用寿命。

在HPLC色谱柱中,填料的选择非常重要。

不同的填料具有
不同的化学性质和分离能力,因此可以根据需要选择合适的填料来实现对目标物质的有效分离。

常见的填料包括正相填料、反相填料、离子交换填料等。

正相填料是指填料表面具有亲水性质,适用于分离亲水性物质。

反相填料则是指填料表面具有疏水性质,适用于分离疏水性物质。

离子交换填料则是指填料表面具有带电性质,适用于分离带电物质。

除了填料的选择外,色谱柱的尺寸也是需要考虑的因素之一。

色谱柱的长度和内径会直接影响到分离效果和分离速度。

一般来说,较长的色谱柱可以提供更好的分离效果,但也会增加分
析时间。

而较小的内径则可以提高分离速度,但也会降低分离效果。

此外,色谱柱还需要进行适当的保养和维护,以确保其长期稳定的工作。

常见的保养措施包括定期清洗色谱柱、更换保护层和填料等。

总之,HPLC色谱柱是HPLC系统中不可或缺的组成部分,它的选择和使用对于保证分析结果的准确性和可靠性至关重要。

因此,在进行HPLC分析时,我们应该根据样品特性和分析要求选择合适的色谱柱,并且合理使用和维护色谱柱,以获得满意的分离和分析效果。
