U(H)PLC Guard Column ACQUITY BEH Amide, 130 Å, 1.7 µm, 2.1 x 5 mm, 3 pc/PAK

ACQUITY BEH Amide columns retain extremely polar compounds, including carbohydrates and sugars. Based on BEH technology the ACQUITY Amide columns offer a chemically stable, trifunctionally bonded amide phase that is stable from pH 2 to 12 to enable the separation of polar analytes that span a wide range of polarity, structural moiety and pKa. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
