Optimize Technologies EXP Guard Column Cartridge, 1mm x 5mm, C4, 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.

Sepax Technologies Inc Sepax HPLC Column PolyRP-NP10, Guard cartridge with holder, 2 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.
