Optimize Technologies EXP Trap Cartridge, 1mm x 5mm, 3.0µm EXP, 3.0µm EXP, Phenyl-Hexyl, 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.

Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP1.7, 2 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.
