Waters Corp XSelect HSS C18 SB VanGuard Cartridge, 100à , 5 µm, 2.1 mm X 5 mm, 3/pk
XSelect HSS C18 SB VanGuard Cartridge, 100à , 5 µm, 2.1 mm X 5 mm, 3/pk
Waters Corp XSelect HSS C18 Prep Guard Cartridge, 100Å, 5 µm, 10 mm X 10 mm, 1/pk
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.
Waters Corp XBridge Premier BEH C18 VanGuard FIT Column, 3.5 μm, 2.1 x 50 mm
This robust column for method development uses BEH C18 sorbent, operating across a mobile phase pH range of 1 to 12. Its trifunctionally bonded C18 ligand suits most LC separations with broad pH compatibility, excellent low pH stability, and minimal column bleed. It delivers high performance for HPLC assays and facilitates UPLC transition. MaxPeak High Performance Surface hardware minimizes analyte interactions, improving peak shape and maintaining signal intensity.

Optimize Technologies EXPGuard Column Cartridge, 1.5mm x 5mm, C8, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
