Standard sample is referred to as standard sample or physical standard. It is developed according to the need of implementing and formulating the character standard. As a supplement to the character standard, the material is a kind of standard material agent of the Institute of Chinese Medicine standards. Simply put, the standard sample is the physical standard, it is another form of the standard, it and the text standard together to form a complete standard form. So, what are the main uses of standard samples? Next, Bolinda Xiaobian to introduce it to you.

What are the main uses of standard samples:

1. Application in laboratory capability verification.

Through the testing of standard samples, both the personal ability of the monitoring and analysis personnel can be verified, and the testing ability of the laboratory can be verified. The former is such as certification assessment, the latter is such as laboratory quality control assessment. The ability verification of standard samples has been widely used in laboratory accreditation, metrological certification and related supervision and review.

2. Application in the establishment of environmental monitoring system quantity traceability.

By using the national standard samples that have been established for traceability to carry out inter-laboratory quantification and quantification comparison, it will effectively improve the comparability of inter-laboratory detection and analysis data. National environmental standard sample is the basic tool of quantity transfer and quantity traceability in China's environmental monitoring system.

The above content is the introduction of the main uses of standard samples, in addition, priority should be given to the use of certified standard samples approved by the state, the use of unlicensed standard samples or self-matching samples instead of standard samples will cause too much financial, material and human waste, not to mention the accuracy, comparability and traceability of quantitative values.
