Optimize Technologies EXP Trap Cartridge, 1mm x 5mm, 3.0µm EXP, 3.0µm EXP, HILIC, 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.

Mac-Mod Avantor Prevail C18, 110 Å, 5 µm, 4.6 x 7.5 mm Guard Cartridges (3/pk)
Avantor Prevail HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. Avantor Prevail HPLC columns are silica based except for Prevail Carbohydrate ES. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes. Avantor Prevail HPLC columns are stable from highly organic to highly aqueous. Avantor Prevail HPLC columns are specialty phases for specific applications. Avantor Prevail HPLC columns provide excellent sensitivity with microbore and ELSD applications.
