Techsphere NH₂ is a silica-based HPLC column with an aminopropyl (NH₂) bonded phase, designed for the analysis of carbohydrates, polar compounds, and applications in normal-phase as well as HILIC (hydrophilic interaction chromatography) mode. The aminopropyl functionality provides strong polar interactions and weak anion-exchange behavior, offering flexible selectivity.
Originally developed by Grace / Alltech and acquired by Dr. Maisch HPLC GmbH in 2016, Techsphere NH₂ has been trusted for its robust performance, high reproducibility, and broad applicability across multiple industries.
Techsphere NH₂ combines polar selectivity and flexible chromatographic modes – a reliable choice for carbohydrate and polar compound separations.
