Solid-Phase Extraction (SPE) is a widely used and popular sample preparation technology that uses solid adsorbents to adsorb target compounds in liquid samples with samples. The matrix and the interfering compound are separated, and then eluted with an eluent or desorbed by heating to achieve the purpose of separating and enriching the target compound. Based on the traditional liquid-liquid extraction, it uses the similar principle of similarity between substances and combines the basic knowledge of liquid chromatography and gas chromatography stationary phases.
Solid phase extraction device

● Anti-cross-contamination, anti-atomization vacuum tank design, easy and fast operation.
• No phase separation operation makes it easy to collect analyte components and process small volume samples.
●The solid phase extraction unit can be equipped with a large-capacity collection container, which can process samples in batches or process samples individually.
●The vacuum chamber is formed by special hard glass mold, and its wall thickness is uniform, so it can withstand high negative pressure above -0.085Mpa.
●The extraction column tray is made of special polymer material, which is beautiful and corrosion resistant and does not deform under high pressure for long-term use.
●The internal test tube rack is made of polytetrafluoroethylene and therefore has high corrosion resistance.
