HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column PolyRP-1000, Guard cartridge with holder, 5 µm, 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-C8, Guard cartridge with holder, 5 µm, 300 Å, 4 x 10 mm
Bio-C8 phase is made of monomeric and fully endcapped chemistry. The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C8 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins.
Optimize Technologies EXP Trap Cartridge, 2.1mm x 5mm, 3.0µm EXP, 3.0µm EXP, SAX, 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.
