Solid Phase Extraction (SPE) is a sample pretreatment technology developed from the mid-1980s. By liquid-solid extraction and liquid chromatography technology developed from the combination. The separation, purification and enrichment of the samples were realized by selective adsorption and desorption of the sample components through solid phase packing. The main purpose is to reduce the sample matrix interference, improve the detection sensitivity.
The basic principle and method of solid phase extraction:
SPE is based on the theory of liquid-solid phase chromatography, which is a kind of physical extraction process including liquid phase and solid phase by means of selective adsorption and selective elution. The sample can also be enriched, separated and purified. As a simple chromatographic process.
Solid phase extraction (SPE) is a liquid chromatography separation principle using selective adsorption and selective elution. The more common method is to make the liquid sample through an adsorbent, to retain the test substance, and then use the appropriate strength of the solvent to impurity, and then with a small amount of good solvent eluting the measured substance, so as to achieve rapid separation and purification purposes. Can also be selective to interfere with impurities, and let the material out; or at the same time adsorption of impurities and the measured substances, and then use the appropriate solvent to selectively elute the measured substance.
Starlab provides SPE products, including Conventional SPE Column,Polymetric SPE Column,and Dedicated SPE Columns. We provides SPE OEM service in order to support you to establish your own SPE brands easily.
