Ultra pure, spherical high performance HPLC phase based on silica gel
Amino modification (Aminopropyl)
4 % carbon content (without endcapping)
Properties
Separation mechanism: Hydrophilic and ionic interactions
Key features:
Multi mode column for RP, NP, HILIC and IC, Aminopropyl modification without endcapping, outstanding mechanical and chemical stability
Technical Data:
Amino phase based on ultra-pure silica gel (purity > 99 %), metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 2 μm, 3 μm, 5 μm, 10 μm (15 μm, 20 – 45 μm on request)
Recommended application areas:
Most flexible phase in the Eurospher II family; can be used in three modes: normal phase, reversed phase and ion chromatography mode (weak anion exchanger); different selectivity to the silica packing; in reversed phase mode mainly used for analysis of carbohydrates
