Application Advantages Of SPE
SPE cartridge
A solid-phase extraction device is a physical extraction process involving a liquid phase and a solid phase. In the solid-phase extraction process, the adsorption of the solid relative analyte is greater than that of the sample mother liquor. When the sample passes through the solid-phase extraction cartridge, the analyte is adsorbed on the solid surface, and the other components pass through the column with the sample mother liquor, and finally the appropriate the solvent takes off the analyte. It is widely used in the fields of medicine, food, environmental protection, commodity inspection, pesticide residues, etc.
