Nucleosil NH2 氨基柱

※ Nucleosil 高性能硅膠，特殊技術(shù)鍵合，使NH2鍵合相在水相介質(zhì)中穩(wěn)定，低流失，保證柱子長壽命※ 鍵合相采用非端基封尾，具有更廣泛的選擇性※ 有100, 120 and 300 Å，三種孔徑；有3um, 5um, 7um, 10um 四種粒度

※ pH stability at 20 °C: 2–8, carbon content 3.5 %※      可以使用多種流動相體系，分析不同性質(zhì)樣品：
    * 正相流動相（正乙烷，二氯乙烯，異丙醇），分析苯胺取代物，酯類和有機氯農(nóng)藥
    * 水和有機物作為正相流動相，可以分析極性樣品，如：糖類、植物甙類
    * 反相中添加緩沖鹽，作為弱離子交換體系可以分析有機酸類，陰離子化合物

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 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)

Available pore sizes 100, 120 and 300 Å, available particle sizes 3 µm, 5 µm, 7 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

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.
