TSKgel Amide-80, 5 µm, 80 Å, 4.6x100mm

TSKgel Amide-80 columns are packed with 2, 3, 5, or 10 µm spherical silica particles that are covalently bonded with carbamoyl groups. The amide stationary phase provides a unique selectivity under regular normal phase conditions or in the hydrophilic interaction mode of chromatography.

TSKgel Amide-80 columns possess superior stability in aqueous/organic solvent systems, an advantage over other hydrophilic stationary phases. In addition, TSKgel Amide-80 columns are ideally suited for sensitive LC/MS analysis of water-soluble polar compounds because the high organic content in the mobile phase provides rapid evaporation of solvent during electrospray ionization.

Target applications for the TSKgel Amide-80 columns include the analysis of saccharides, glycans, oligosaccharides, peptides, and other polar compounds. The stationary phase does not react with reducing sugars and can be used at elevated temperatures (4 to 80 °C) to prevent peak splitting of carbohydrates that can occur at lower temperatures.
