NUCLEODUR NH2

NUCLEODUR® NH2 / NH2-RP
high purity silica phase for HPLC
aminopropyl modification for NP and RP separations 2.5 % C · not endcapped · USP L8
Features

	key features: 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
	technical characteristics: aminopropyl-modified high purity silica; pore size 110 Å, particles sizes 3, 5 and 7 µm; 2.5 % C; not endcapped
	recommended application: 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

Guard collumns in packs of 3, columns in packs of 1.
* Guard column cartridges are coupled to EC columns using guard column adaptor EC (REF 721359). 3 mm ID ChromCart® (CC) guard column cartridges (.30) are used for 2 mm ID and 3 mm ID EC columns; 4 mm ID (.40) CC guard column cartridges are applied for 4 and 4.6 mm ID EC columns.
Custom-packed EC columns with oder dimensions are available on request.
