1. On-line moisture determination method
Online moisture determination methods include MOSYE online microwave moisture analyzer, MS-580 online near infrared moisture analyzer, online infrared moisture analyzer and online neutron moisture analyzer.
1, online microwave moisture analyzer
On-line microwave moisture analyzer can be divided into contact and non-contact online microwave moisture analyzer. The MS- 100 series of contact on-line microwave moisture analyzer adopts the unique microwave time difference technology, has built-in various patented software algorithms, and combines the advanced manufacturing technology in Germany, thus forming a unique technical advantage. The non-contact on-line microwave moisture analyzer MS-590 adopts the latest multi-spectrum hardware technology in the world and the unique patented algorithm of fuzzy data analysis combined with the data model structure, which can realize completely independent measurement of moisture content and density without affecting each other. It is the latest and most advanced penetrating multi-spectrum microwave moisture analyzer in the world.
2. On-line Near Infrared Moisture Analyzer
On-line near infrared moisture analyzer MS-580, which adopts the latest multi-spectrum near infrared hardware technology and unique patented algorithm combined with data model structure to realize on-line moisture measurement, is the latest and most advanced near infrared moisture analyzer in the world.
3. Online infrared moisture analyzer
On-line infrared moisture analyzer, based on the principle that water absorbs infrared rays with specific wavelength, has good water measurement selectivity for multi-component materials, and is very suitable for continuous on-line and non-contact moisture measurement. Using infrared technology can fundamentally avoid the wear of traditional moisture meter contact probe or the nuclear radiation of radioactive source probe, and ensure safety, stability, rapidity, accuracy and durability.
4, online neutron moisture analyzer
The detection principle of on-line neutron moisture analyzer is based on the fact that neutrons are sensitive to H element in water, which can slow down neutrons, while other substances have almost no such process. Because the online neutron moisture analyzer uses radioactive sources, it is gradually eliminated and faded out of the market.
Second, the laboratory moisture determination method
Laboratory moisture determination methods include Karl Fischer moisture analyzer, Coulomb moisture analyzer and dew point moisture analyzer.
1, Karl fischer method. It is a classic method, also known as micro-moisture analyzer, which is mainly used to detect samples with low moisture content. After improvement, the accuracy is greatly improved and the measurement range is expanded.
2, dew point moisture meter. The operation is simple, the instrument is not complicated, and the measured results are generally satisfactory. It is often used to determine trace moisture in permanent gases. However, this method has a lot of interference, and some easily cold-exchanged gases will condense before water vapor, especially when the concentration is high.
3. Coulomb moisture analyzer. It is often used to determine the moisture content in gas. This method is simple in operation and quick in response, and is especially suitable for the determination of trace moisture in gas. If it is determined by general chemical methods, it is very difficult. However, the electrolytic method is not suitable for the determination of alkaline substances or conjugated dienes.
4. Halogen moisture analyzer is a new type of rapid moisture detection instrument. Using ring halogen lamp for heating, intelligent operation. It can quickly and evenly dry samples, obtain accurate moisture determination results and clear moisture determination information display, and realize intuitive, simple and convenient instrument operation.
