1. Overview of Thermo-gravimetric Analyzer

Thermo-gravimetric analyzer is a precision laboratory equipment that analyzes and studies the thermal stability and composition of materials by measuring the mass change of materials during heating. Thermo gravimetric analyzer is widely used in many fields such as materials science, chemistry, physics and environmental science, providing researchers with an important tool for in-depth understanding of the properties of materials.

2. Working Principle and Application

The working principle of thermo-gravimetric analyzer is based on a series of physical and chemical changes that may occur in substances during heating. These changes may include the discharge of water or volatiles, chemical reactions in a specific atmosphere, oxidation, etc., resulting in a decrease or increase in the mass of the substance. By accurately measuring these mass changes, researchers can reveal the special properties and stability of the material, and then evaluate and improve the performance of the material.

3. Key Components and Technical Features

Heating System

One of the cores of the thermo-gravimetric analyzer is its heating system. The system uses a high-temperature resistant U-shaped silicon molybdenum rod as a heating element, which can work stably at temperatures up to 1650°C to ensure uniform heating of the sample. This design makes the heating process more efficient while ensuring the accuracy and repeatability of the experimental results.

Weighing system

The high-precision integrated weighing system is another key component of the thermo gravimetric analyzer. The system has a weighing range of 0-500g/0-210g and a weighing accuracy of 0.001g/0.0001g. This means that even small mass changes can be accurately captured and recorded, providing researchers with rich data support.

Measurement and control software

The measurement and control software equipped with the thermo-gravimetric analyzer can realize microcomputer temperature program control, including multiple modes such as constant temperature rise, temperature drop, constant temperature and circulation. During the experiment, the temperature and mass data are recorded in real time by the software, which is convenient for researchers to conduct subsequent analysis and processing.

Ventilation device

The ventilation device is designed with 2 independent ventilation pipelines, each of which is equipped with a rotor flowmeter (accuracy 5%). This design allows users to introduce protective inert gas or mixed gas according to experimental needs. The gas is directly fed into the furnace and diffuses rapidly inside the furnace to create the required environment for the heated sample. In addition, the equipment is also equipped with an exhaust port to ensure smooth and safe gas exchange.

As a thermal analysis instrument, the thermo-gravimetric analyzer provides an important scientific basis for the research and development of materials by accurately measuring the mass change of substances during heating. Its advanced technical features and sophisticated design make it an indispensable analytical tool in the laboratory. Through this equipment, researchers can better understand the thermal behavior of materials, thereby promoting the advancement of science and technology and the development of industry.
