HPLC Guard Columns and Cartridges
YMC America, Inc TMS guard 120A 3um 10x3mm
YMC-Pack TMS columns are bonded with trimethylmonochlorosilane to create a phase with intermediate polarity This makes for a versatile stationary phase that is useful for analysis of extremely hydrophobic compounds using conventional reversed-phase solvents or highly polar compounds using high aqueous solvents The unique chemistry of this packing material is also well-suited for the analysis of multifunctional compounds Selectivity characteristics of a C1 bonded phase can be unique and samples must be evaluated to determine the applicability of the phase

Optimize Technologies EXPGuard Column Cartridge, 3.0mm x 5mm, SAX, 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.
