Toluene moisture analyzer is a precision instrument widely used in chemical, pharmaceutical, food, agriculture and other fields. It uses toluene as a solvent to measure the moisture content in the sample by a specific method. This article will introduce the working principle, characteristics, applications and precautions of toluene moisture analyzer in detail.
How toluene moisture analyzers work.
Toluene moisture analyzers measure moisture based on the soluble properties of toluene in water. At a certain temperature and pressure, toluene is able to dissolve a certain amount of water, and the water content can be determined by measuring the dissolved volume of toluene. The specific operation steps are as follows: the sample is mixed with dried toluene and heated at a certain temperature to fully dissolve the water in the sample. Then, the moisture content in the sample was calculated by measuring the change in the volume of toluene before and after dissolution.
Features of Toluene Moisture Analyzer EJ-400A
1. PLC control system, 7-inch large LCD touch screen control, stable performance, simple and convenient operation;
2. 1-4 groups of samples can be made at a time, and each channel can be controlled independently
3. Far infrared ceramic heating method, bowl-shaped design, high fit, fast heating speed, fast reflux speed, greatly shortening the extraction time;
4. The condenser tube bracket adopts a slide rail design, which is compatible with fixing a variety of standard moisture measuring devices
5. The heating unit has a single hole and a single control, the power of 0-500w can be adjusted arbitrarily, and the system presets the micro-boiling mode and time control, which does not need to be supervised, so as to ensure the safety of the machine for long-term use
6. External chiller, circulating water cooling, no need to connect to natural water, save water, and at the same time, the refrigeration effect is good, and it can be used for a long time to ensure the experimental effect.
Application of toluene moisture analyzer.
Chemical industry: In the chemical industry, many substances need to be produced and used under conditions with strictly controlled moisture content. Toluene moisture analyzers can be used to monitor the moisture content of chemical raw materials, intermediate products, and final products.
2.Pharmaceutical industry: The control of moisture in the drug production process is very strict, which is directly related to the quality and efficacy of drugs. Toluene moisture analyzers provide a reliable means of detection for the pharmaceutical industry.
3.Food industry: The moisture content of food has a significant impact on its taste, shelf life and nutritional value. Toluene moisture analyzers can quickly and accurately determine the moisture content in food, which helps to control food processing and storage.
4.Agriculture: The moisture content in the soil is essential for the growth of crops. By using a toluene moisture analyzer, agricultural researchers can accurately measure the water content in the soil, providing a scientific basis for rational irrigation.
5.Other fields: In addition to the above application fields, toluene moisture analyzer can also be used in moisture detection in many industries such as environmental protection, petroleum, and new energy.
Precautions for using a toluene moisture analyzer.
1.Safety issues: Toluene has a certain toxicity, and personal protective equipment should be worn during operation to ensure that it is carried out under good ventilation conditions.
2.Operation specification: Follow the instrument operating procedures to ensure the accuracy of the measurement results. Sample handling and instrument calibration are performed according to standard procedures to obtain reliable data.
3.Maintenance: Regularly clean and maintain the instrument to keep it in good working condition. If there is a fault, ask a professional to inspect and repair it.
4.Waste disposal: For used toluene solvents, they should be disposed of in accordance with relevant regulations to avoid environmental pollution.
VI. Conclusions. Toluene moisture analyzers play an important role in many industries as an efficient moisture measurement tool. Understanding its working principle, characteristics, applications and precautions can help to better play its advantages and provide strong support for quality control and research in various industries. With the continuous progress of technology, it is believed that toluene moisture analyzer will be applied and promoted in more fields.
