1. The infrared moisture analyzer is simple to operate, takes less time, and has accurate measurement results. Therefore, the infrared moisture analyzer can be widely used in experimental analysis, daily purchase control and process testing in chemical, pharmaceutical, food, tobacco, grain and other industries.
2. Karl Fischer's method is a classic method. After improvement in recent years, the accuracy has been greatly improved and the measurement range has been expanded. It has been listed as a standard method for the determination of moisture in many substances.
3. The microwave moisture analyzer uses microwave field to dry the sample, which accelerates the drying process. It has the characteristics of short measurement time, convenient operation, high accuracy and wide application range. It is suitable for particles of grain, paper, wood, textiles and chemical products. It can also be applied to the determination of moisture in petroleum, kerosene and other liquid samples.
4. The infrared moisture analyzer is easy to operate, the instrument is not complicated, and the measured results are generally satisfactory. It is often used for the determination of trace moisture in gas. However, this method has more interference, and some gases that are easy to be cooled and exchanged, especially when the concentration is high, will condense before water vapor and cause interference.
5. Coulomb moisture analyzer is often used to measure the moisture content in gas. This method is easy to operate and quick to respond, and is especially suitable for the determination of trace moisture in gas. It is very difficult to measure by a general chemical method. However, electrolysis is not suitable for the determination of alkaline substances or conjugated diolefins.
