ACQUITY Premier BEH Amide Columns retain extremely polar compounds, including carbohydrates and sugars. Based on BEH technology the ACQUITY Premier Amide Columns offer a chemically stable, trifunctionally bonded amide phase that is stable from pH 2 to 11 to enable the separation of polar analytes that span a wide range of polarity, structural moiety and pKa. ACQUITY Premier Columns use MaxPeak High Performance Surface hardware technology which significantly reduces unwanted analyte/surface interactions that can lead to poor peak shape and losses in signal intensity. The VanGuard FIT Column design protects the column from contaminants and increases column lifetime
