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.
