SPE Technology Brief Introduction
The extraction is divided into liquid phase extraction (LLE) and solid phase extraction (SPE). SPE technology is a column chromatography separation process. The technology is a combination of liquid-solid extraction and column liquid chromatography. The combination of this technology improves the disadvantage of the low recovery rate of the analyses by traditional liquid-liquid extraction method, improves the recovery efficiency, makes the separation between the interferer and the analyses more effective, reduces the sample pretreatment process, and is simple to operate, time-saving and labor-saving.
Common method
SPE is the separation principle of selective adsorption and selective elution by liquid chromatography. The more commonly used method is to make the liquid sample solution pass through the adsorbent to retain the substance to be measured, and then select the appropriate strength of the solvent to flush the impurities, and then use a small amount of solvent to quickly elution of the material to be measured, so as to achieve the purpose of rapid separation and purification and concentration. It can selectively adsorb interfering impurities and let the measured substance flow out. Or adsorb both impurities and the material to be measured, and then use the appropriate solvent to selectively elution of the material to be measured.
