Full-automatic nuclide solid-phase extraction device and method

Abstract

The invention discloses a full-automatic nuclide solid-phase extraction device. The device mainly solves the problem of inaccurate analysis results caused by human factors in the extraction and analysis process of environmental samples. The extraction device comprises a device shell, an automatic column packing system arranged in the device shell and used for preparing a chromatographic column, asample stock solution column passing system arranged in the device shell and matched with the automatic column packing system to make a sample stock solution pass through the column, a reagent column-passing system is arranged in the device shell and matched with the automatic column-packing system and the sample stock solution column-passing system to make extraction reagents pass through the columns in sequence, and a touch screen arranged on the device shell and electrically connected with the automatic column-packing system, the sample stock solution column-passing system and the reagent column-passing system. By means of the design, the device has the advantages of being high in reliability, convenient to use and the like, the problem that the analysis result is inaccurate due to human factors in the extraction and analysis process of environmental samples is solved, the working efficiency and the experiment precision can be improved, and the labor intensity of experimenters is reduced.

Description

technical field [0001] The invention relates to the technical field of radionuclide analysis in environmental samples, in particular to a fully automatic nuclide solid-phase extraction device and an extraction method. Background technique [0002] When analyzing nuclides such as strontium-90 and plutonium in environmental samples, ion exchange and extraction chromatography are often used, that is, the sample solution is passed through an ion exchange column or extraction column, so as to separate and purify the sample to be measured from other elements. Since the separation and purification steps of the sample solution through the column are cumbersome and lengthy, and take up a lot of analysis time, the entire extraction step is mechanized and automated, and a nuclide solid-phase extraction device is developed to replace the manual nuclide extraction analysis. [0003] At present, domestic manufacturers of instruments and equipment have developed the separation, enrichment ...
