HPLC Guard Columns and Cartridges
Waters Corp XTerra MS C18 Sentry Guard Cartridge, 125Å, 3.5 µm, 2.1 mm X 20 mm, 2/pk
XTerra MS C18 columns are general purpose, hybrid-based, reversed-phase C18 columns that are designed to be compatible with mass spectrometry applications. These first generation columns provide superior pH stability compared to a silica-based column.
Waters Corp XBridge BEH Shield RP18 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.

YMC America, Inc ODS-A 5UM 200A 20X4MM PK/5
AA20S05-0204GC: ODS-A, 5um, 200A, 20X4mm Cartridge, pk/5
Optimize Technologies EXP Trap Cartridge, 2.1mm x 5mm, 2.7µm HALO, C18, 3pk
The Hand-Tight EXP™ Trap Column is rated to 20,000+ psi. This unique design connects directly to any injection valve (with 10-32 threads) or in-line with 1/16” tubing for unparalleled convenience and efficiency. The EXP™ System enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. Free-Turn™ architecture allows users to change cartridges by hand without breaking fluid connections on the holder inlet/outlet. The EXP™ Trap Column family now offers packed beds available in 2, 5, 10, 15, 20 and 30mm lengths with diameters ranging from 1-4.6mm and bed volumes from 1.6-600µL. Please contact your representative directly if you're interested in a length other than 5mm.
