FAQ
What Are Some Strategies For Solid Phase Extraction? There are a number of ways SPE can be approached using a Sep-Pak C18 6 cc Vac Cartridge. Purification entails using a chemical filter to retain the component of interest while interferences elute, or to retain the interferences while the analyte passes through unretained.
