Problems solved by technology

[0003] The process of putting the sample into the detection instrument after digestion requires manual hand-held inspection. The operation is cumbersome, time-consuming, easy to be polluted and lost, and directly affects the analysis results.
[0004] However, with the increasing maturity of science and technology, a new technology has emerged in the sample digestion method, which uses external radiation to digest the sample, but this technology only stays in the simple way of directly irradiating the ultraviolet lamp without any A complete set of brand new instruments and equipment for inspection

Abstract

Disclosed is a sample digestion and heavy metal detection integrated device. The sample digestion and heavy metal detection integrated device comprises a housing, a digestion chamber, a detecting chamber and a vertical baffle, wherein the digestion chamber is used for digesting samples; the detecting chamber is used for detecting digested samples; the vertical baffle is used for being embedded into the housing for separating the inside of the housing into the digestion chamber and the detecting chamber; the inside of the digestion chamber is provided with a heating disc, a conveying disc, a detecting disc and an ultraviolet radiant lamp; the inside of the detecting chamber is provided with a detector, a detecting disc, a swing arm, a rotating rod, a bearing and a motor, one end of the swing arm is arranged on the rotating rod, the other end of the swing arm is fixedly provided with a conveying disc, the top inside the digestion chamber is provided with the ultraviolet radiant lamp, thebottom inside the digestion chamber is provided with the heating disc, the conveying disc connected with the swing arm is suspended above the heating disc, and the conveying disc and the swing arm can rotate horizontally around the rotating rod inside the digestion chamber onto the detecting disc at the bottom of the detecting chamber. The sample digestion and heavy metal detection integrated device combines sample digestion and heavy metal detection and achieves intelligent operation from digestion to detection as well as ultraviolet radiation.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an integrated device for sample digestion and heavy metal detection. Background technique [0002] At present, in the process of detecting heavy metals in food, soil, and water quality, samples are often digested by wet digestion and dry ashing to destroy the organic matter or surface active substances in the sample. All forms of heavy metals (including arsenic, arsenic, Lead, cadmium, chromium, mercury, nickel, iron, aluminum, zinc, manganese, copper, etc.) are converted into ions, dissociated from organic complexes to form water-soluble inorganic salts, and the sample is digested Afterwards, the heavy metal content was obtained through metal detection equipment analysis. [0003] The process of putting the sample into the detection instrument after digestion requires manual hand-held inspection. The operation is cumbersome, time-consuming...
