The invention provides a solid-phase extraction column sealing device and a solid-phase extraction instrument, and relates to the technical field of solid-phase extraction devices. The solid-phase extraction column sealing device comprises a cover body, and the cover body can be connected with a liquid inlet of a solid-phase extraction column in a sealed mode; a needle penetrating hole is formed in the cover body; the cover body is also provided with a sealing lip, and the sealing lip can be hermetically connected with the outer wall of a sampling needle; the solid-phase extraction instrumentcomprises a solid-phase extraction column, the sampling needle and the solid-phase extraction column sealing device. The solid-phase extraction column sealing device is used for sealing the liquid inlet of the solid-phase extraction column, and when the sampling needle needs to be drawn out of the solid-phase extraction column to be cleaned, no sealing ring is arranged on the sampling needle, so that no cleaning dead angle exists, and cleaning is convenient.
Description
technical field [0001] The invention relates to the technical field of solid phase extraction devices, in particular to a solid phase extraction column sealing device and a solid phase extraction instrument. Background technique [0002] Solid-phase extraction (Solid-Phase Extraction, referred to as SPE) is a sample pretreatment technology developed in recent years. It is developed from the combination of liquid-solid extraction and column liquid chromatography. It is mainly used for the separation, purification and concentration of samples. . The solid phase extraction column is a cylindrical device with openings at both ends for solid phase extraction, and the upper opening is the liquid inlet, and the lower end is the liquid outlet. The device is equipped with two plugs, and the two plugs are filled with adsorption The liquid enters the solid phase extraction column from the liquid inlet, and is discharged from the liquid outlet after passing through the adsorbent.
