SPE Disks and Cartridges
Waters Corp Sep-Pak Silica 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55 - 105 µm, 30/pk
A polar stationary phase, used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons or less polar esters and ethers. Analyte retention can occur through hydrogen bonding, dipole-dipole interactions or in aqueous samples through cation-exchange.
Waters Corp Oasis MAX 1 cc Flangeless Vac Cartridge, 10 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless Oasis MAX cartridges contain the Oasis MAX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting acidic compounds with anion-exchange groups. Since the Oasis MAX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
