In chemical and industrial production, a solids analyzer is an important measuring instrument used to measure the content of solid components in a substance. Solids analyzers have a wide range of applications and can be used to measure the solid content of various types of substances, such as powders, granules, fibers, emulsions, etc. This article will introduce the principle, classification, use method and precautions of the solid content tester to help readers better understand and master the use of this instrument.
First, the principle of the solid content tester.
The principle of the solid content tester is mainly to determine the solid content of a substance by measuring its mass and volume. Specifically, when a substance is heated to a certain temperature, volatile substances such as moisture and solvents in it will volatilize, while solid components will be retained. By measuring the mass and volume changes of the species before and after volatilization, the mass and volume of the solid components can be calculated, and then the solid content can be obtained.

Second, the classification of solid content testers.
Solid content tester can be divided into two types: drying tester and drying tester. The drying method tester calculates the solid content by heating the substance to a certain temperature so that the water in it can fully evaporate, and then measuring the change in the mass of the substance. Desiccators, on the other hand, heat the substance to a higher temperature so that all the moisture and solvent in it evaporate, and then measure the mass change to calculate the solids content.
3. How to use the solid content tester.
The use of a solids analyzer needs to be carried out by following these steps:
1.Prepare the sample: The substance to be measured is ground into powder or small particles for better measurements.
2.Weigh the sample: Use a balance to weigh the quality of the sample and record it.
3.Loading: Place the sample in a measuring cup to ensure that the sample is evenly distributed in the cup.
4.Start Measurement: Turn on the power of the solids analyzer, adjust the measurement parameters, then place the measuring cup on the instrument and press the start button to measure.
5.Wait for the measurement to complete: Wait for the measurement to complete and read the solids value displayed by the instrument.
6.Clean up the instrument: Use tools such as brushes to clean up the debris inside the instrument.
4. Precautions.
When using a solid content tester, you need to pay attention to the following:
1.Make sure the instrument is placed on a stable table so as not to affect the measurement accuracy.
2.When weighing samples, use a high-precision balance to ensure the accuracy of the measurement results.
3.When loading, it is necessary to ensure that the sample is evenly distributed, and there is no accumulation or void.
4.When using the drying tester, make sure that the heating temperature and time are sufficient to allow the water to evaporate sufficiently.
5.When using a desiccation tester, make sure that the heating temperature is high enough that all moisture and solvent evaporates.
6.When cleaning the instrument, it is necessary to pay attention to safety to avoid accidents such as scalding.
7.In the process of use, it is necessary to pay attention to the maintenance and maintenance of the instrument to ensure its service life and measurement accuracy.
In conclusion, a solids analyzer is an important measuring instrument that can help us quickly and accurately measure the content of solid components in a substance. By understanding its principles, classifications, usage methods and precautions, we can better grasp the skills and methods of using this instrument.
