| Project Background

The experimental background of TGA testing (Thermogravimetric Analysis) stems from the scientific research and industrial needs for the mass change law of substances under programmed temperature control. Its core value lies in revealing the thermal stability, compositional decomposition behavior, volatile content, and chemical reaction processes of materials, providing crucial data support for material design, process optimization, and quality control.

| Project Overview

Thermogravimetry Analysis (abbreviated as TG or TGA) is to measure the relationship between the mass of a sample and temperature or time under programmed temperature control and a certain atmosphere. The record obtained by TGA is the thermogravimetric curve (TG curve). The curve obtained by taking the first-order derivative of TG curve with respect to temperature or time is the derivative thermogravimetric curve (DTG curve, which is an important supplementary representation of TG signal).
