Abstract

The invention provides a reagent management device and extraction equipment, and relates to the field of solid-phase extraction. The reagent management device comprises a box body, a reagent container, a weighing assembly and a controller. The weighing assembly is arranged in the box body. The reagent container is placed on the weighing assembly. The weighing assembly is connected with the controller. The weighing assembly of the reagent management device weighs the residual amount of a reagent without being influenced by fluctuations of the liquid level of the reagent, so that the detection precision of the residual amount of the reagent is high. Even if a capacitive liquid level sensor cannot reliably detect or even cannot detect the residual amount of the reagent with a weak dielectricconstant, the residual amount can also be accurately detected.

Description

technical field [0001] The invention relates to the field of solid phase extraction, in particular to a reagent management device and 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] SPE cartridges or samples are processed with different reagents during SPE. A variety of reagents are used in the...
