Standard sample refers to the standard substances used in the national drug standards for identification, inspection, content determination, impurity and related substance inspection, and it is an integral part of the national drug standards. The national drug standard material is the material basis of the national drug standard, which is a special measuring tool used to check the quality of drugs. It is the benchmark for measuring drug quality; It is also used as a material standard for calibration of test instruments and methods. So what are the precautions for the use of standard samples? The following is a small edition of Bolinda to introduce you.

What are the precautions for the use of standard samples:

First, when selecting a standard sample, its matrix composition must be close to the sample being tested, which is very important, only in this way can it eliminate the systematic error caused by the matrix effect. Only by using such a standard sample can the accuracy of the data obtained be higher, and whether the tested sample can meet the standard can be more clear.

Second, as we all know, many standard samples have a shelf life, when buying standard samples, we must look at the effective period. When it is used, it is also necessary to check the production date and expiration date, and it must be used within the validity period of the standard sample. In addition, if the storage is not proper, even within the expiration date, the standard sample will deteriorate, and the deteriorated standard sample can not continue to be used.

Third, the standard sample used must be the same as the chemical composition of the sample being tested as much as possible, which must be clear.

The above content is the introduction of the precautions for the use of standard samples, in short, it is a special item for measuring standards, its value is very important, for many enterprises that need to use standard substances is indispensable. If you want the standard sample to be able to play a more effective role when used, then we need to strictly abide by its use method.
