產(chan) 品介紹
什麽(me) 是親(qin) 水作用色譜
親(qin) 水作用色譜是一種直接分離極性和親(qin) 水性化合物的色譜技術,為(wei) 了便於(yu) 理解,我們(men) 可以把它看作為(wei) 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(qin) 水性的固定相
•以水、有機溶劑和緩衝(chong) 鹽做為(wei) 流動相洗脫劑
常見的HILIC方法采用50-90%有機溶劑和一定比例的水,並且含有低濃度的緩衝(chong) 鹽。如:乙腈/水/醋酸銨體(ti) 係。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 medium length 150 mm column is suitable for most applications, including gradients. |
