Sepax Technologies Inc Sepax HPLC Column GP-C8, 3 µm, 120 Å, 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.

Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 3 µm, 200 Å, 2 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.

Optimize Technologies EXP Trap Cartridge, 4.6mm x 5mm, 3.0µm EXP, 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.
Optimize Technologies EXPGuard Column Cartridge, 3.0mm x 5mm, C4, 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.
