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 150458
概述 SeQuant® ZIC®-HILIC is the ideal choice for separation of polar and hydrophilic compounds. The high-performance, truly zwitterionic stationary phase, ensures reproductible retention of all types of compounds that have poor retention and are difficult to separate on reversed-phase HPLC columns. ZIC®-HILIC is designed for compounds such as acids and bases, anions and cations, carbohydrates, metabolites, metal complexes, amino acids, peptides, protein digests and much more. This long 250 mm column is suitable for very complex samples.
