Thermogravimetric Analysis (TGA) for Precise Material Insights
Thermogravimetric Analysis (TGA) is a thermal analysis technique that measures changes in a material's mass as a function of temperature or time under a controlled atmosphere.
It is widely used to characterize material composition, thermal stability, and decomposition behavior.

What is Thermogravimetric Analysis (TGA)?
TGA provides critical insight into a material's thermal behavior and composition in a single test. It allows for identification of moisture content, volatiles, organic vs. inorganic content, and thermal degradation points.
This technique delivers high-resolution, quantitative data ideal for material screening, formulation studies, quality control, and material analysis.
Our Process
Sample Preparation
Solid or semi-solid sample (10–50 mg) is prepped and conditioned.
Load into TGA
Sample is placed on a microbalance inside a temperature-controlled furnace.
Heat & Measure
Under inert or reactive gas, the sample is heated while mass changes are recorded.
Analyze Results
Mass-loss data is used to assess thermal stability, composition, and decomposition.
