Sepax HPLC Guard Cartridge, with Holder, GP-C4, 120 Å, 3 μm, 4 x 10 mm

Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
