產品介紹
什麼是親水作用色譜
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☁✘│，為了便於理解☁✘│，我們可以把它看作為是一種用反相色譜溶劑做流動機動的正相色譜↟•✘☁☁。
因此HILIC是✘•₪₪✘：
•親水性的固定相
•以水││◕◕◕、有機溶劑和緩衝鹽做為流動相洗脫劑
常見的HILIC方法採用50-90%有機溶劑和一定比例的水☁✘│，並且含有低濃度的緩衝鹽↟•✘☁☁。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☁✘│，保留時間越長

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. |
