Embodiment Construction

[0023] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the present invention. It should be understood that while the invention has been described in connection with preferred specific embodiments thereof, these embodiments are illustrative only and are not intended to limit the scope of the invention.

[0024] Such as image 3 As shown, the present invention relates to a solid phase extraction column, which includes a hollow column body 1, two sieve plates 2, 3 are arranged inside the column body 1, and a filler 4 is arranged between the two sieve plates 2, 3. The filler 4 is an adsorbent, and the adsorbent is silica gel or activated carbon, which is used to adsorb the solid particles in the solution flowing through the column 1 . The two sieve plates 2 and 3 are made of polypropylene or glass fiber material to prevent...

Abstract

The invention provides a solid-phase extraction column which effectively solves the problems that an extraction column in the prior art is large in size, large in the using amount of filling material, large in the using amount of a solution for elution and high in extraction operation cost. The invention discloses a solid-phase extraction column which includes a hollow column body; two sieve plates are disposed inside the hollow column body; and the filling material is arranged between the two sieve plates. The advantages of the present invention are that: the size of the solid-phase extraction column is effectively reduced, the using amount of the filling material is effectively saved, the using amount of the solution for washing out is reduced and the cost of raw material and extraction operation is significantly reduced. In addition, the flow velocity of the solution can be ensured. The extraction column is simple to operate and convenient to wash.

Description

technical field [0001] The invention relates to a solid particle sampling device, in particular to a solid phase extraction column. 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 liquid chromatography technology. 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 the analyte, more effectively separate the analyte from the interfering components, reduce the sample pretreatment process, simple operation, save time and effort, and is widely used in medicine, food, environment, Commodity inspection, chemical industry and other fields. The solid-phase extraction column is a sample pretreatment device developed from a chromatography column for extraction, separation, and con...
