HILIC Amide HPLC Columns Description
The HILIC column adopts a polar modified stationary phase, which enhances the retention capacity of some strongly polar compounds and effectively overcomes the shortcomings of reversed-phase chromatography of poor retention of such compounds. Unlike traditional reversed-phase chromatography columns, HILIC columns only require a small amount of water in the mobile phase to retain strongly polar compounds, and the increase in the organic phase is beneficial to improve the detection sensitivity of compounds
HILIC amide HPLC column, the stationary phase is based on ultra-pure fully porous spherical silica gel, using the unique phase-bonding technology of Hawach Scientific, bonding carbamoyl functional groups, through special surface modification technology, very good. Its hydrophilicity and stability have a longer life than the amino column. It can effectively separate sugars, peptides and low molecular weight polar compounds, and is the best choice for replacing the amino column in hilic mode.
HILIC Amide HPLC Columns Characteristics
Uniform pore size distribution and uniform hydrophilic polymer covering the surface of the silica gel enables efficient separation of highly polar and hydrophilic compounds;
It can be used as a column for hydrophobic interaction analysis and is widely used in the analysis of peptides, nucleotides, glycosides and hydrophobic drugs;
A unique bonding process to ensure that the stationary phase is more stable in aqueous organic mobile phases;
Suitable for LC/MS analysis of water-soluble polar compounds.
