SPE Disks and Cartridges
Waters Corp Sep-Pak C8 Plus Light Cartridge, 145 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Sep-Pak Porapak RDX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 125-150 µm, 30/pk
Specially cleaned polymeric poly(divinylbenzene-vinylpyrrolidone) resin with hydrophobic character. Can be used as an alternative to octadecyl-bonded silica for preparation of analytes that weakly adsorb to silica-based reversed-phase sorbents. Compatible with sample or eluents at high and low pH. Specifically designed for the concentration of high explosives in aqueous samples.
Waters Corp Sep-Pak C8 Plus Short Cartridge, 400 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Oasis MAX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc 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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Oasis MCX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
The 3 cc Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX 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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Silica 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 55 - 105 µm, 20/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 PSA 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50/pk
Sep-Pak PSA 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50/pk
Waters Corp Oasis MCX 3 cc Flangeless Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
The 3 cc flangeless Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX 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.
Waters Corp Oasis MAX Plus Short Cartridge, 225 mg Sorbent per Cartridge, 60 µm, 50/pk
Oasis MAX Plus Short 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 60 µm particle size is recommended when working with viscous samples. These versatile Plus Short cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
