Waters XSelect HSS C18 Sentry Guard Cartridge, 100Å, 3.5 µm, 3 mm X 20 mm, 2/pkg - 186004764

The HSS C18 is a general-purpose C18 bonded phase column that provides superior peak shape for bases, increased retention (vs. XBridge C18 columns), and exceptional column lifetimes at low pH. The selectivity and retention observed with HSS C18 columns will resemble that of most modern, fully endcapped, high-coverage silica-based C18 columns.
