A reference is a standard item used to measure a standard value. In daily life and work, small partners are certainly rarely heard of this kind of item. With the rapid development of the economic era, many bioassays, chemical assays, physical assays and so on will use this kind of reference for further research. Do you know what are the ways to distinguish this type of control product? The following is a small edition of Bolinda to introduce you.

Reference substance refers to the reference substance used for identification, inspection, content determination and calibration of the performance of the calibration instrument, while the reference substance refers to the reference substance used for the determination of content or titer in biological assays, antibiotics or biological drugs, expressed in the titer unit (U). In the copywriting records often confuse the two concepts, that the reference product is the standard product, is a substance two kinds of reference only, the reason for the error may be that some drugs have both reference products and standard products.

For example, when the titer of cefaclor is determined by microbiological method, the standard of cefaclor is used, and the reference is used when the titer is determined by HPLC or UV method. When phenacetin is used as a melting point calibration substance, the melting point standard is used, and the content is determined with a reference. Even if the standard and the reference of the same substance, their specifications, calibration methods and uses may be different.

The above content is to teach you to distinguish the method of introduction, all in all, when we distinguish the reference products, we can focus on observing their obvious characteristics, and then use professional methods to distinguish the reference products, so that the conclusion will be more professional. Like some research institutes, some research is carried out specifically for the service of consumers, in order to meet the needs of consumers.
