In the 1980s, the development of standard substances has entered the stage of universal promotion and use all over the world. Environmental reference material has not only become the reference material for conveying accuracy in environmental testing, but also the material basis for the quality control of laboratory analysis. In the world, there are nearly a thousand environmental reference substances. So what exactly is the environmental reference material possibility? The following is a small edition of Bolinda to introduce you.

In fact, the environmental reference material is only one type of reference material:

Environmental reference substances, also known as environmental reference substances, are reference substances that are similar to the environmental substances being measured in composition and properties. As the current instrumental analysis method is only a relative measurement method, the standard reference material should be used to correct the instrumental analysis to exclude the drying and influence caused by the amount of the measured component and the measurement signal, so as to obtain a more accurate measurement value.

Application of environmental reference materials in environmental monitoring:

Acceptance and calibration of environmental monitoring instruments Environmental standard substances are often used in the verification of compulsory verification instruments by metrological supervision departments, so that these instruments can be traced to national standards; At the same time, in the daily analysis and testing work, environmental standard substances are often used to calibrate the instrument to control the accuracy and precision of the measurement. If the self-prepared standard solution is used, it is not only time-consuming and laborious, but also easy to introduce errors, and it is difficult to make the analysis results comparable.

The above content is the introduction of what is the environmental standard material. With the strengthening of environmental management and the development of environmental science, the scope of environmental monitoring is becoming wider and wider, and the comparability, consistency and reliability of environmental monitoring data are more important. As the basis of quantity transfer and quality assurance, the preparation and use of environmental reference materials have been paid more and more attention and gradually standardized.
