HPLC Guard Columns and Cartridges
Waters Corp XTerra Shield RP18 Sentry Guard Cartridge, 125Å, 5 µm, 2.1 mm X 20 mm, 2/pk
XTerra RP18 columns are general purpose, hybrid-based, reversed-phase C18 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column.
Waters Corp XTerra Shield RP8 Prep Guard Cartridge, 125Å, 5 µm, 10 mm X 10 mm, 1/pk
XTerra Preparative RP8 columns are hybrid-based, reversed-phase C8 columns that incorporate Waters patented embedded polar group technology to improve peak shape performance for highly basic compounds. These first generation columns provide superior pH stability compared to a silica-based column. This product needs to be used in conjunction with other parts.

Waters Corp Symmetry C18 Prep Guard Cartridge, 100Å, 7 µm, 7.8 mm X 10 mm, 1/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
Waters Corp XTerra MS C18 Prep Guard Cartridge, 125Å, 5 µm, 10 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.

Optimize Technologies EXP Guard Column Cartridge, 1mm x 5mm, C18, 1.8µm, 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.
