solid phase extraction(Solid-Phase Extraction,abbreviationSPE)It is a widely used and popular sample pretreatment technique,It is to use solid adsorbents to adsorb target compounds in liquid samples,Separation from the matrix and interfering compounds of the sample,Then use eluent to wash or heat to desorb,To achieve the goal of separating and enriching target compounds. It is in traditional liquid—Based on liquid extraction, the principle of similar solubility between substances is adopted, combined with the basic knowledge of widely used liquid chromatography and gas chromatography stationary phases.

JQThe solid-phase extraction device has the following structural characteristics:

1Anti cross contamination, anti atomization vacuum chamber design, simple and fast operation.

2The phase free separation operation is easy to collect analyte components and can handle small volume samples.

3Can be equipped with large capacity collection containers, can process samples in batches or individually.

4The vacuum chamber is formed using a special hard glass mold, and its wall thickness is uniform, so it can withstand85KpaThe above high negative pressure.

5The extraction column tray is made of ultra-high polymer material, which is beautiful, corrosion-resistant, and does not deform under high pressure for long-term use.
