ZIC®-HILIC亲水作用色谱柱

直接分离极性和亲水性化合物

两性离子基因通过共价键合在多孔硅胶上

超长的耐受性使得样品分离的成本很低

 

什么是亲水作用色谱

亲水作用色谱是一种直接分离极性和亲水性化合物的色谱技术,为了便于理解,我们可以把它看作为是一种用反相色谱溶剂做流动机动的正相色谱。

因此HILIC是:

亲水性的固定相

以水、有机溶剂和缓冲盐做为流动相洗脱剂

常见的HILIC方法采用50-90%有机溶剂和一定比例的水,并且含有低浓度的缓冲盐。如:乙腈//醋酸铵体系。在HILIC方法中,洗脱顺序和反相色谱正好相反,即极性越大,保留时间越长

ZIC-HILIC PEEK HPLC Column
描述
产品目录编号 150662
概述 SeQuant® ZIC®-cHILIC is designed for improved separation of polar hydrophilic compounds that have proved difficult to separate by reversed-phase HPLC or previous types of HILIC columns. The orientation of its zwitterionic functional group provides more accessible positive charges, which results in a complementary selectivity with more retention particularly for organic acids and other negatively charged compounds. Especially suitable for LC-MS thanks to an extraordinary high column stability and a minimized column bleed. This long 250 mm column is suitable for very complex samples.
