Adsorbosphere NH2 is an aminopropyl-modified silica phase designed for HILIC, normal-phase, and specialized carbohydrate separations. The NH₂ functional group introduces polar retention properties and weak anion-exchange characteristics, making it highly versatile for separating hydrophilic and neutral compounds.
This phase is particularly well suited for sugar and sugar alcohol analysis, as well as polar pharmaceuticals and food additives. Adsorbosphere NH2 provides stable retention and fast equilibration in acetonitrile-rich eluents, enabling reproducible performance in gradient and isocratic modes.
Adsorbosphere NH2 is a go-to phase for hydrophilic compound analysis – delivering flexibility across multiple chromatographic modes with a single, robust platform.
