Overview

Thermogravimetric analysis (TG, TGA) is a technique that observes the continuous changes in weight or weight percentage of a test sample as it heats up, maintains a constant temperature, or cools down. Its purpose is to study the thermal stability and composition of materials. It is widely used in the research and development, process optimization, and quality control of various fields, including plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metals, and composites. This instrument employs a microbalance with a sensitivity of one part per million, Curie point temperature calibration, a gas mass flow meter, perfect sealing to ensure consistent intake and exhaust, and is convenient for users to collect data.
