Hypersil GOLD PEI HILIC HPLC columns retain highly polar analytes which are difficult to analyse with conventional reversed phase columns. The tertiary amine functionality from the polyethyleneimine bonding shows anion-exchange activity with good hydrophilic selectivity making it suitable for the analysis of acidic or neutral polar compounds. Based on fully porous high-quality silica with 1.9 µm, 3 µm and 5 µm particle sizes, the Hypersil GOLD PEI HILIC columns are ideal for applications within drug discovery, food testing and environmental analysis.
Features
- Fully porous silica particles with selectivity for HILIC separations
- Recommended for acidic or neutral polar molecules
- 1.9 µm, 3 µm, and 5µm particle sizes for all separation needs
- Enhanced sensitivity in MS
- Alternative to ion-pair or derivatization methods
- Outstanding peak shape and selectivity
