In the analysis work, it is often necessary to use a compound of good quality and accurate content, which is used as a comparison for detection control, or used to calibrate the instrument. This compound is called a standard. Or standard. The standard product refers to the standard substance used to determine the potency of biological products. The production department must provide the standard product expressed in units (μ) of its potency when it is approved as a quality standard for biological products. According to the application, the standard products for inspection can be divided into biological standard products for biological verification of biological products, endocrine drugs, antibiotics and so on.
