Description of NH2 Column

The NH2 HPLC column uses the innovative filler bonding technology unique to Hawach. It is based on ultra-high purity and all-hole spherical silica gel. It bonds with aminopropyl functional groups, and through the strict process, control ensures the formation of even dense amino functional groups. The molecular layer maximizes bond coverage and ensures excellent column packing.

NH2 column is suitable for most normal phase chromatography applications. It can also be used as a stationary phase for hydrophilic interaction chromatography for positive phase analysis of polar compounds, weak anion exchange, and aqueous reverse-phase liquid phase analysis. This column is widely used for the analysis of low molecular weight sugars such as glucose, fructose, xylose, and lactose. It can replace most of the amino HPLC columns on the market.
