Hamilton HxSil C18 5 µm Column, 4.6 x 250 mm

Silica-based C18 columns (PN: 79889) are one of the most widely used reversed-phase HPLC columns. Hamilton offers two alkylated silica columns: HxSil C18 and HxSil C8. C18 columns are more hydrophobic than C8 columns and thereby retain hydrophobic analytes more strongly than a C8 column will.
