Embodiment

[0025] like figure 1 As shown, the suction nanofiber solid-phase extraction column filling device includes a pressure tank 1 that is sealed, and the notch of the pressure tank 1 is provided with a sealing block 2 for fixing the solid-phase extraction column 4, and a negative pressure tank 1 is arranged outside the pressure tank 1. Pressure extraction device 3, the negative pressure extraction device 3 communicates with the pressure tank 1 for negative pressure suction.

[0026] The sealing block 2 is provided with several fixing holes 21, the solid phase extraction column 4 is fixed with the fixing holes 21, and the extraction channel in the solid phase extraction column 4 communicates with the pressure tank. The negative pressure extraction device 3 is an air pump.

[0027] like figure 2 As shown, when filling the suction nanofiber SPE column, first fix the SPE column on the suction nanofiber SPE column filling device; immerse the nanofibers in the filling liquid; then fil...

Abstract

The invention discloses a filling device of a suction nanometer fiber solid phase extraction column, comprising a pressure groove (1) which is sealed, wherein the opening of the pressure groove (1) is provided with a sealing block (2) which is used for fixing the solid phase extraction column (4), and the outer side of the pressure groove (1) is provided with a negative pressure extracting device (3). The negative pressure extracting device (3) and the pressure groove (1) communicate with the negative pressure to pump. The solid phase extraction columns after being filled have same tightness, and the filling work efficiency is greatly improved. Because of the manual operation process of the filling operation, the production in batches can be easily realized.

Description

technical field [0001] The invention belongs to the technical field of separation, and in particular relates to a suction nanofiber solid-phase extraction column filling device and its application. Background technique [0002] Solid-phase extraction (Solid-Phase Extraction, referred to as SPE) is an effective means of separation and purification of trace or trace substances. It is a sample pretreatment technology developed in recent years. It is developed by combining liquid-solid extraction and column liquid chromatography. It is mainly used for the separation, purification and concentration of samples. Compared with the traditional liquid-liquid extraction method, it can improve the recovery rate of analytes, more effectively separate analytes from interfering components, reduce the sample pretreatment process, and is easy to operate. ,save time and energy. Widely used in medicine, food, environment, commodity inspection, chemical industry and other fields. [0003] Nan...
