SPE Disks and Cartridges
Waters Corp Oasis HLB Plus Light Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 50/pk
Oasis HLB sample extraction products contain a polymeric water-wettable reversed-phase sorbent. When combined with a simple, generic methodology, HLB sorbent allows the extraction of a wide range of compounds in various matrices with high reproducible recoveries.
Waters Corp Oasis WAX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 30/pk
Oasis WAX weak anion-exchange SPE chemistry is designed for scientists searching for a fast, simple and highly selective method for sample preparation and cleanup. Oasis WAX is a polymeric reversed-phase, weak ion exchange mixed-mode sorbent that allows for the retention and release of strong acidic compounds (e.g. phosphonates). The elution solvent is MS friendly and the sorbent is completely water wettable.
Waters Corp Sep-Pak Silica Classic Cartridge, 690 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Polar sorbent, used primarily to adsorb analytes from non polar solvents like hydrocarbons, chloro- or flouro-substituted hydrocarbons or less polar esters and ethers.
Waters Corp Sep-Pak Accell Plus CM Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Plus Light cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
