A reference substance is a substance or material that has been determined to have one or more sufficiently uniform characteristic values, and is used as a "measuring tool" in the analytical measurement industry to calibrate measuring instruments and devices, evaluate measurement analysis methods, measure the characteristic values of substances or materials, and assess the operational skills of analysts. As well as in the production process of product quality control and other fields play an indispensable role. Then do you know what are the characteristics of national standard substances? Next, Bolinda Xiaobian to introduce it to you.

Analysis of the characteristics of national standard materials:

1,The quantity value of the national standard substance is related to the nature of the substance, but has nothing to do with the quantity and shape of the substance.

2, with good reproducibility, can be prepared in batch and after the use of unlimited copy.

3, there are many types of national standard substances, only the chemical component of the standard substance is thousands, its quantity range across 12 orders of magnitude, can meet the different needs of all walks of life.

4, the standard material is relatively practical, can be used in the actual working conditions for a good application, so that it can be used to calibrate the measurement instrument, and then evaluate the accuracy of the measurement method, but also can be used for the quality evaluation of the measurement process and laboratory measurement certification and measurement arbitration.

The above content is the introduction of the characteristics of the national standard material, for the characteristics of the national standard material, I believe that we have some understanding of it. Now the rapid development of China's standard material industry, thanks to the rapid development of China's measurement instruments, so that China's standard material authority to further improve, international recognition in the world to provide reference.
