Solid phase extraction instrument

Principle of Solid Phase Extraction Instrument: The solid phase extraction device consists of a solid phase extraction column and auxiliary components. The solid-phase extraction column consists of three parts: column tube, sintering pad, and packing. SPE accessories generally include vacuum systems, vacuum pumps, blow drying devices, inert gas sources, large capacity samplers, and buffer bottles. Solid phase extraction is a physical extraction process that involves both liquid and solid phases. In solid-phase extraction, the adsorption force of the separated substance is greater than that of the solvent used to dissolve the separated substance. When the sample solution passes through the adsorbent bed, the separated substances concentrate on its surface, while other sample components pass through the adsorbent bed; By using adsorbents that only adsorb the separated substance without adsorbing other sample components, high-purity and concentrated separated substances can be obtained.

Solid phase extraction technology, abbreviated as SPE, is widely used in fields such as medicine, chemical engineering, and environment. Solid phase extraction technology should have been developed in recent years and is a sample pretreatment technique. Mainly used for sample separation, purification, and concentration. Compared with traditional solid-phase extraction technology, the developed solid-phase extraction technology can improve the recovery rate of analytes and more effectively separate analytes from interfering components. Reducing the pre-treatment process of samples, solid-phase extraction technology is now easy to operate, time-saving, and labor-saving.
