Solid phase extraction (SPE) cartridges are used in the sample preparation sample clean up with DEXTech pure. It is basically a sample preparation method to clean samples prior to analysis. The stationary phase in the SPE cartridges selectively adsorbs target analytes while permitting interference-causing chemicals to pass through. By experimenting with various circumstances and parameters including flow rates, solvent volumes, and wash/elution solvents, you should make sure the process works best for your particular application. Sample preparation sample clean up with DEXTech pure will facilitate the finest sample preparation and analytical outcomes possible. It is a go-to option for users in dioxin/PCB analysis.
