◇      可以使用多种流动相体系，分析不同性质样品：
◇ 正相流动相（正乙烷，二氯乙烯，异丙醇），分析苯胺取代物，酯类和有机氯农药◇ 水和有机物作为正相流动相，可以分析极性样品，如：糖类、植物甙类
◇ 反相中添加缓冲盐，作为弱离子交换体系可以分析有机酸类，阴离子化合物

NUCLEOSIL? NH2 / NH2 RP
Amino modified silica phases for HPLC · USP L8

Features
	Polar aminopropyl modified silica for reversed phase and normal phase chromatography: Normal phase chromatography with hexane, dichloromethane or 2-propanol as mobile phase for polar compounds such as substituted anilines, esters, chlorinated pesticides Reversed phase chromatography of polar compounds like carbohydrates in aqueous-organic eluent systems Anion exchange chromatography of anions and organic acids using common buffers (e.g., acetate or phosphate) in conjunction with organic modifiers (e.g., acetonitrile) Pore size 100 ?, available particle sizes 3 μm, 5 μm, and 10 μm, pH stability at 20 °C: 2–8, carbon content 3.5 % Separation mechanism based on polar interactions, hydrophobic interactions and weak ion exchange interactions Corresponding NUCLEODUR? phase see NUCLEODUR NH2 / NH2-RP

EC standard columns for analytical HPLC
Ordering information
Eluent in column (except for NUCLEOSIL? 100-5 NH2 RP) is n-heptane. When using an eluent which is not miscible with n-heptane (e.g., water), it is necessary to rinse the column with THF first.
