什么是親水作用色譜
親水作用色譜是一種直接分離極性和親水性化合物的色譜技術(shù)，為了便于理解，我們可以把它看作為是一種用反相色譜溶劑做流動(dòng)機(jī)動(dòng)的正相色譜。
因此HILIC是：
•親水性的固定相
•以水、有機(jī)溶劑和緩沖鹽做為流動(dòng)相洗脫劑
常見(jiàn)的HILIC方法采用50-90%有機(jī)溶劑和一定比例的水，并且含有低濃度的緩沖鹽。如：乙腈/水/醋酸銨體系。在HILIC方法中，洗脫順序和反相色譜正好相反，即極性越大，保留時(shí)間越長(zhǎng)

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 medium 150 mm column is suitable for most applications, including gradients. Its small pore size of 100 Å have larger surface area that give additional retention and selectivity. |
