NUCLEODUR^® – Amino (NH2 & NH2-RP)

• Multi-mode columns (for RP, NP, and IC)
• Stable against hydrolysis at low pH (working range pH 2-8), 100% stable in water; suitable for LC/MS
• Widens scope of analytical HPLC into the polar range

Aminopropyl-modified high purity silica; pore size 110 Å, particles sizes 3 µm, 5 µm, and 7 µm; 2.5% C; not endcapped

• Polar compounds under RP conditions (sugars, DNA bases), hydrocarbons under NP conditions
• Normal phase chromatography (NP) with hexane, dichloromethane or 2-propanol as mobile phase for polar compounds such as substituted anilines, esters, chlorinated pesticides
• Reversed-phase chromatography (RP) of polar compounds in aqueous-organic eluent systems
• Ion exchange chromatography of anions and organic acids using conventional buffers and organic modifiers
