Thermogravimetric Analyzer

Instrument Introduction:

Thermogravimetric analysis (TG, TGA) is the process of observing the changes in the mass of a sample with temperature or time during heating, constant temperature, or cooling, with the aim of studying the thermal stability and composition of the material. Widely used in research and development, process optimization, and quality monitoring in various fields such as plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials, and composite materials.

Thermogravimetric analyzer SR-TGA-1250Purpose:

Measure and study the following characteristics of materials: thermal stability, decomposition process, adsorption and desorption, oxidation and reduction, quantitative analysis of composition, effects of additives and fillers, moisture and volatile compounds, reaction kinetics, etc.

Thermogravimetric analyzer SR-TGA-1250Key Features:

1. Built in imported quality weighing balance, with internal calibration and temperature compensation functions, can quickly respond to quality changes, and has better accuracy and repeatability;

2. The instrument has a built-in quality level guidance function, and changes in sample position within the scale range do not affect the quality results;

3. The internal balance room is equipped with a constant temperature water bath device to ensure constant temperature, greatly improving the stability of weighing;

4. The instrument can perform experiments on sample weight gain or loss, such as the adsorption and decomposition processes of the sample;

5. The closed ceramic insulation furnace body structure greatly improves signal sensitivity and resolution, and can obtain a more stable baseline;
