It is very important to choose a suitable moisture analyzer, because the moisture content of different substances is different, so it is necessary to choose a suitable instrument for measurement.
At present, there are many methods for measuring moisture in the market, which can be divided into thermogravimetry, infrared method, microwave method, gas chromatography and so on according to different principles. ?
Thermogravimetric method is a commonly used method to measure moisture content, and its principle is to calculate moisture content by measuring the weight change of samples at high temperature. Thermogravimetric method is suitable for moisture determination of most solid samples, such as food, pharmacy and chemical industry.
Infrared method is to determine the moisture content of the sample by measuring the energy absorbed, transmitted or reflected by infrared rays. The infrared method does not need to process the sample, and is simple to operate, so it is suitable for large-scale sample detection. ?
Microwave method is a new method for moisture determination, which uses the characteristics of microwave to heat the moisture in the sample and measure the reflected or transmitted microwave energy of the sample, thus calculating the moisture content of the sample. Microwave method is fast and suitable for large-scale detection and online detection. ?
Gas chromatography is a more accurate method for moisture determination, which uses gas chromatography to detect moisture in samples. Gas chromatography has the characteristics of high precision and high sensitivity, and is suitable for the determination of some special moisture, such as the determination of extremely small residual moisture. ?
Generally speaking, selecting a suitable moisture analyzer needs to be considered comprehensively according to the actual demand and sample characteristics. In addition to the performance and price of the instrument itself, after-sales service, maintenance and other factors need to be considered.
When choosing a moisture analyzer, you also need to know the standard and operation process of the instrument. Different moisture determination methods have different standards and need to be selected according to the actual situation. In the process of operation, you must read the instructions carefully and follow the operating procedures to ensure the accuracy and reliability of the measured data.
In short, moisture analyzers are widely used in various industries. Choosing the right instrument and quantifying it correctly is an important guarantee to ensure product quality and production efficiency.
