The national standard material has a wide range of applications in our chemical field and biological field, and it is a special instrument for measurement. In our production, work and life, we can always come into contact with a variety of substances, and the national standard substances, standard solutions, pharmacopoeia, reagents and other substances have corresponding standards and reference products. So what are the characteristics of the national standard material? The following is a small edition of Bolinda to introduce you.

What are the characteristics of the national standard material:

1, the standard material in the national standard material network has good reproducibility, can be prepared in batches and reproduced after use.

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

3, the national standard material is practical, can be applied under actual working conditions, can be used to calibrate measuring instruments, evaluate the accuracy of measurement methods, can also 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, the national standard material has its own characteristics are very much, extremely practical and can be used under actual working conditions; There are many kinds of them; It has very good reproducibility and can be prepared in batch. The properties of matter are closely related to its scale, and the shape of matter is also closely related to the quantity of matter. The national standard material is of great help to the experimentalists, providing them with accurate data and reducing errors, which is the main reason why the national standard material is widely used in our country.
