Medicines are a special commodity. The quality of medicines is directly related to human life and health. Strict quality control in the production process of medicines is a reliable measure to ensure the quality of medicines and the safety and effectiveness of people ’s medicines. Therefore, medicines The quality consciousness of the production enterprises is becoming stronger and stronger, and the requirements for drug quality testing are becoming higher and higher, and higher requirements are placed on the technical performance of the moisture analyzer used for testing.
There are many methods for determining the moisture content. The most commonly used method in the pharmaceutical industry is the Karl Fischer method to determine the moisture content in the sample. In the pharmaceutical industry, the moisture content of a variety of raw materials, intermediates and finished products must be measured, because the state of the tested samples is diverse (for example: finished products include tablets, suppositories, lyophilized drugs, and certain active substances. Form), the presence of water in the tested sample is different. Free water, crystalline water, and the pharmaceutical ingredients contained in the tested sample will affect the measurement. Therefore, when determining the moisture content of the drug, the physical Properties and chemical properties, choose different solvents and Karl Fischer reagents.
The AKF-2010 new intelligent Karl Fischer moisture analyzer is a new generation of moisture analyzer developed by Hegong Scientific Instruments combined with domestic and foreign moisture measurement technology, applying new data communication technology and control software based on computer operating system. The test acceptance results show that the performance index of the AKF-2010 smart card moisture meter has reached the level of similar products of international advanced brands. The instrument can be used in medicine, food, chemical products and other solids, liquids, and gases. It is suitable for Karl Fischer. Analysis of moisture in samples tested by the method.
