Introduction:Shanghai Jingxin solid phase extraction device/solid phase extraction instrument/chromatographic pretreatment QSE-36B

Shanghai Jingxin Solid Phase Extraction Unit/Solid Phase Extraction Apparatus/Chromatography Pretreatment QSE-36B Product Introduction:

Solid-Phase Extraction (Solid-Phase Extraction, referred to as SPE) is a widely used and popular sample pretreatment technology. The matrix and the interfering compound are separated, and then eluted with the eluent or heated to desorb to achieve the purpose of separating and enriching the target compound. It is developed based on the traditional liquid-liquid extraction based on the principle of similar intermiscibility with similar effects between substances and combined with the basic knowledge of liquid chromatography and gas chromatography stationary phases that are currently widely used.

Main features of solid phase extraction device:

●Each channel is equipped with an imported regulating valve, which can adjust the flow rate according to the test requirements.

●Unique spiral disk support design can freely adjust the height and flexibly combine support disks with different apertures to meet most sampling test tubes.

●The vacuum degree can reach 0.098Mpa when used with FCD vacuum pump.

●The unique waste liquid collection bottle separates the extraction part from the waste liquid storage part, which not only prevents cross-contamination, but also makes it more convenient to dispose of waste liquid

●The extraction column tray is made of special polymer material, which is beautiful and corrosion-resistant and will not be deformed under high pressure for long-term use.

●The internal test tube rack is made of PTFE, so it has high corrosion resistance.
