SPE Disks and Cartridges
Waters Corp Certified Sep-Pak Silica 3 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Certified Sep-Pak Silica Vac cartridges contain a polar sorbent that is used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons, or less polar esters and ethers. Certified Sep-Pak Silica Vac cartridges can also be used in an aqueous medium as a cation exchanger of intermediate strength. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments. Certified Sep-Pak Silica cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low-level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C18 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/pk
Sep-Pak C18 Vac cartridges contain a hydrophobic, reverse-phase, silica-based bonded phase that is used to adsorb analytes of even weak hydrophobicity from aqueous solutions. The Sep-Pak C18 sorbent is made using the most reproducible bonding technology available, utilizing monofunctional silane chemistry. This sorbent offers a unique selectivity and excellent recovery of anlytes, and is recommended as a general purpose SPE phase for both polar and non-polar analytes. Typical applications include extraction of drugs and their metabolites in serum, plasma or urine, desalting of peptides, isolation of trace organics in environmental water samples and organic acids in beverages. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak Dry Sodium Sulfate, Plus Long Cartridge, 2.85 g, 50/pk
Waters Sep-Pak Dry cartridges are packed with 2.85g of anhydrous sodium sulfate. These cartridges are designed to remove residual water from the SPE extract.
Waters Corp Sep-Pak C18 Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Silica-based bonded phase with strong hydrophobicity; used to adsorb analytes of even weak hydrophobicity from aqueous solutions; typical applications include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages; similar in behavior to reversed-phase HPLC columns.
