Adsorbosil NH2 is a versatile aminopropyl-modified (NH₂) silica phase designed for multiple chromatographic modes including normal-phase, HILIC, and specialized carbohydrate analysis. The polar amino functionality allows strong dipole interactions, making this phase ideal for separating hydrophilic and weakly basic compounds.
In normal-phase mode, Adsorbosil NH2 provides retention for polar compounds using non-polar eluents such as heptane. In reversed-phase or HILIC mode, it is well-suited for sugars, sugar alcohols, and other small polar molecules using acetonitrile-water or methanol-water mixtures.
Adsorbosil NH2 is a powerful tool for specialized analytical tasks requiring polar retention, HILIC functionality, or carbohydrate-specific selectivity.
Adsorbosil NH2 is a good alternative to Polygosil® NH2.
