Medicine is a special kind of commodity. The quality of a drug is directly related to human life and health. Strict quality control in the production process of drugs is a reliable and effective measure to ensure the quality of drugs and the safety of people. Therefore, drugs The quality awareness of production enterprises is getting more and more concentrated, and the requirements for quality inspection of drugs are getting higher and higher, and the technical performance of the rapid moisture analyzer used for testing is also put forward higher requirements.
In the production process of medicines, water content is an important indicator for testing the quality of medicines. The level of water content will directly affect the quality of medicines, and will also affect the service life of medicines. Therefore, in the production and quality control of medicines, Strictly control and test the moisture content of the drug.
There are several methods for determining the moisture content. Currently, the most common method in the pharmaceutical industry is to use the Karl Fischer method to determine the moisture content of the sample. In the pharmaceutical industry, the moisture content of various raw materials, intermediates and finished products is determined. The state of the sample to be tested is varied (eg, the finished drug has tablets, suppositories, freeze-dried and certain active substances). Form), the presence of moisture in the sample to be tested is different, there are free water, crystal water, and the pharmaceutical ingredients contained in the sample to be tested, so the measurement of the moisture content of the drug depends on the physical properties of the drug. Nature and chemical properties, using different solvents and Karl Fischer reagents.
The MA-1 Smart Karl Fischer Moisture Analyzer is a volumetric intelligent moisture analysis system jointly developed by the R&D Department of Shanghai Benang Scientific Instrument Co., Ltd. and the Fifth Institute of China Ordnance Industry Group. It adopts a large-screen LCD liquid crystal display with a touch screen. It has rich software content, Chinese character prompts for operation, flexible and convenient human-machine dialogue, and storage and printing of test results. In 2010, he cooperated with the State Key Laboratory of Precision Testing Technology and Instruments of Tsinghua University, and further improved it with ultra-precision displacement measurement technology. The measurement precision has made a qualitative leap and reached the world's top level.
MA-1 intelligent Karl Fischer moisture analyzer is widely used in universities, research institutes, quality inspection institutions, pharmaceuticals, chemical companies, fertilizers, pesticides, dyes, coatings, food and beverage, surfactants, cosmetics, etc. Testing of raw materials, intermediates and finished products.
