Problems solved by technology
[0004] The object of the present invention is to provide a kind of extracting and enriching device for trace components in a rotating repetitive sample, to solve the problem of the existing sample extracting and enriching device for trace components in the above-mentioned background technology, due to the inability to repeatedly process the liquid This problem will greatly affect the quality of liquid agent enrichment, and reduce the accuracy of trace element extraction. At the same time, the sample column cannot be rotated, so that the liquid agent is not mixed enough, which affects the problem of the device's liquid agent treatment.

The invention discloses a rotary repeatable extraction and enrichment device for trace components in a sample, comprising a main body shell of the extraction and enrichment device, a liquid agent injection port and an electric push rod are provided on the upper surface of the main shell of the extraction and enrichment device. It is fixedly installed under the interior of the main body shell of the extraction and enrichment device, and an enrichment column installation outer shell is arranged above the electric push rod, and an inner pillar is fixedly installed behind the enrichment column installation outer shell. Compared with the prior art, the present invention provides a rotary repeatable device for extracting and enriching trace components in samples, which has the following beneficial effects: the device for extracting and enriching trace components can rotate the sample column, so that the sample is The mixing inside the sample column is more uniform, and the device can also choose two different ways of manual rotation and motor-driven rotation, and can also make the liquid agent circulate and enrich, which can make the device more thoroughly enrich the liquid agent.
Description
technical field [0001] The invention relates to the technical field of a device for extracting and enriching trace components in a sample, in particular to a device for extracting and enriching trace components in a rotating and repeating sample. Background technique [0002] In the field of analytical chemistry, most samples need to be pretreated, that is, to convert the sample into a form that can be measured or to separate the measured components from the interfering components, so as to carry out qualitative and quantitative analysis. Separation, extraction and enrichment techniques are of great significance in the pretreatment of substance separation and detection. The separation method can achieve the effect of eliminating interference and enrichment in quantitative analysis, ensuring the accuracy and reliability of analysis results, and expanding the scope of analysis applications. Therefore, the quality of separation and extraction directly affects the accuracy of t...
