Description

Technical Field

[0001] The invention relates to the technical field of chemical medicine component detection and sampling, in particular to a chemical medicine component detection and sampling device. Background Art

[0002] After processing, chemicals are generally packaged in containers, and labels are affixed to the surface of the containers with the names of the chemicals written on them. When the chemicals are not used for a long time or the storage environment becomes humid, the writing on the labels becomes lighter over time and difficult to accurately recognize. When the chemicals are used frequently, the labels are easily worn out, which also makes the writing difficult to recognize. Therefore, the labels need to be replaced. At this time, in order to ensure that the name of the chemical on the label is correct, the chemicals need to be sampled and tested.

[0003] The traditional sampling method is to directly insert the sampling tube into the chemical for sampling. However, since the surface of the chemical is easily in contact with oxygen and water in the air, its composition may change. If sampling is performed directly and then tested, the test results will be inaccurate. In addition, only one sampling tube is used for sampling, and the sample is single, resulting in unrepresentative test results. If the sampling tube is used for multiple samplings, it takes a long time and the sampling and detection efficiency is reduced. Summary of the invention
