Solid phase extraction referred to as SPE is a widely used and popular sample pretreatment technology. It is separated from interfering compounds, and then eluted with eluent to achieve the purpose of separating and enriching target compounds. SPE is developed on the basis of traditional liquid-liquid extraction (LLE), using the principle of similar compatibility of similar effects between substances and combining the basic knowledge of currently widely used liquid chromatography (HPLC) and gas chromatography (GC) stationary phases.

SPE solid-phase extraction is mainly used to process liquid samples for extracting, concentrating and purifying volatile and semi-volatile compounds in samples; when it needs to be used for solid samples, it is necessary to process the solid samples into liquid state first.

The QSE-24 solid phase extraction device is designed based on the above principles and combined with the actual use process. Under the premise of ensuring the recovery rate of the target compound, it is designed to be convenient for users to operate and use, and improve the efficiency of sample pretreatment.
