Description

Technical Field

[0001] The invention relates to the technical field of medicinal material detection, and more specifically, to a rapid method for detecting pesticide residues and heavy metals. Background Art

[0002] Chinese herbal medicine is a kind of herbal medicine used in traditional Chinese medicine, which is produced in a region with specific natural conditions and ecological environment. At present, Chinese herbal medicine usually needs to be tested for heavy metals, not only for the subsequent processing and use of Chinese herbal medicine, but also for the convenience of users to determine the degree of environmental pollution according to the degree of heavy metal detection, protect ecosystems and biodiversity, assess human health risks, monitor environmental pollution sources and governance effects, and provide a scientific basis for the formulation of environmental protection policies and regulations; currently, when testing for heavy metals in herbal medicines, the Chinese herbal medicines are usually chopped and pulped, and then an appropriate amount of sample is added to a glass container, and some strong acid reagents are added to form a herbal sample liquid, and then the herbal sample liquid is analyzed by analytical equipment.

[0003] In this regard, China has applied for patent number: CN117330625A, which discloses a method for detecting heavy metals in medicinal materials based on I CP□MS technology. The method is applied to a detection device, and the detection device includes a support component, an I CP□MS analyzer, an ICP□MS online sampling device, a lifting module, a horizontal moving component, a beaker component, and a beaker cleaning component; wherein the detection method includes the following steps: S1: After the medicinal materials are processed, a medicinal material sample liquid is obtained, and an appropriate amount of the medicinal material sample liquid is poured into the beaker component; S2: Start the I CP□MS online sampling device, and through the lifting module, the input end of the I CP□MS online sampling device enters the beaker component to extract the medicinal material sample liquid into the I CP□MS analyzer for analysis to obtain the analysis results. After the heavy metals in the medicinal materials are detected by the I CP□MS analyzer and the I CP□MS online sampling device, the inner wall of the beaker body can be cleaned by the beaker cleaning component, which effectively avoids the danger caused by improper operation of the user.

[0004] However, in actual use, the above design can only clean the liquid on the inner wall of the beaker body, but cannot clean the pipeline of the sampling device as a whole. During the sampling process, some heavy metals and pesticide residues will also accumulate inside the pipeline. If they are not cleaned, more heavy metals and pesticide residues will accumulate on the inner wall of the pipeline, which will affect the result of the next test. As a result, the cleaning effect after the overall test is poor, and the beaker body and the pipeline of the sampling device cannot be cleaned in an integrated manner at the same time, which has certain limitations during the overall test.
