Amino (NH2) bonded silica gel phases can be used ideally in the normal phase and HILIC mode. They show alternative normal-phase selectivity to unbonded silica, especially for aromatics.

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

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, metal content < 10 ppm, pH-stability 2 - 8, pore size 100 A, particle size 5 μm
Recommended application areas:
Eurospher NH2 packing material can be universally used in different polar modes (NP, RP and IC). Eurospher NH2 is an excellent choice for carbohydrate analysis in reversed phase mode and can also be used as a weak anion exchanger.
Spherical high performance HPLC phase based on type A silica gel
Amino modification (Aminopropyl), 4.6 % carbon content (without endcapping)
ProntoSIL Amino is an Amino Propyl bonded phase. It can be used in three modes: NP mode, RP mode and IC mode. In the NP mode it is an alternative to the silica packings but offers different selectivities. In the RP mode the packing is mainly used for carbohydrate analysis. In the IC mode the bonded phase can be used as a weak anion exchanger (WAX) for the analysis of anions and organic acids. The packing shows excellent properties in Supercritical Fluid Chromatography (SFC) where dense gases (i.e CO2) are used as mobile phases. The amino-bonding type is available in 120 Å and particle sizes of 3 μm, 5 μm and 10 μm.
Spherical high performance HPLC phase based on type A silica gel
Amino modification (Aminopropyl), endcapped, with 5 % carbon content
ProntoSIL Amino E is an Amino Propyl bonded phase. In comparison to ProntoSIL Amino this support is fully endcapped. It can also be used in three modes: NP mode, RP mode and IC mode (see ProntoSIL Amino). The packing shows excellent properties in Supercritical Fluid Chromatography (SFC) where dense gases (i.e. CO2) are used as mobile phases. Due to the fact that it is fully endcapped it is perfectly suitable for the SFC of basic compounds. ProntoSIL Amino E is only available in 120 Å and 5 μm.
