Abstract

The invention provides a sample tube cleaning device and solid-phase extraction equipment, and relates to the technical field of solid-phase extraction devices. The sample tube cleaning device comprises a sampling probe and a liquid pump, wherein one end of the sampling probe communicates with a liquid outlet of the liquid pump; and a cleaning hole is formed in the other end of the sampling probe.When the sample tube cleaning device is in use, one end, provided with the cleaning hole, of the sampling probe stretches into a sample tube, and the cleaning hole is opposite to the side wall or thebottom wall of the sample tube; and when the liquid pump works, a reagent for cleaning is pumped into the sampling probe and is ejected from the inside of the cleaning hole so as to wash the inner wall of the sample tube. The pressure of the reagent ejected from the inside of the cleaning hole is high, so that a sample on the inner wall of the sample tube is helped to be quickly cleaned thoroughly, the cleaning time is effectively reduced, and the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solid phase extraction devices, in particular to a sample tube cleaning device and solid phase extraction equipment. Background technique [0002] Solid-phase extraction (Solid-Phase Extraction, referred to as SPE) is a sample pretreatment technology developed from the combination of liquid-solid extraction and column liquid chromatography, and is mainly used for the separation, purification and concentration of samples. Compared with the traditional liquid-liquid extraction method, solid-phase extraction can improve the recovery rate of the target, more effectively separate the target from the interfering components, reduce the sample pretreatment steps, simple operation, save time and effort, so it is widely used It is used in medicine, food, environment, commodity inspection, chemical industry and other fields. [0003] In the solid phase extraction process, the sample loading rate directly affects th...
