Thermogravimetric Analysis (TGA)
What is TGA?
Thermogravimetric Analysis (TGA) is a thermal analysis technique that measures the change in mass of a material as a function of temperature or time. It tracks decomposition, oxidation, and other mass-related transitions, making it essential for R&D, production, and failure analysis.
Principle of work:
It provides critical data on:
- Thermal Stability – Determining the temperature at which a material decomposes or loses mass due to volatilization, oxidation, or other reactions.
- Composition Analysis – Identifying filler content, moisture, solvents, or additives by measuring mass loss at specific temperature ranges.
- Oxidative & Decomposition Behavior – Evaluating material resistance to oxidation and decomposition by tracking mass changes under controlled atmospheres (e.g., nitrogen, air).
- Kinetics of Degradation – Studying reaction rates and activation energy by analyzing mass loss patterns under different heating rates.

Applications
- Polymers – Assessing thermal stability for automotive components, flame retardancy in construction materials, and decomposition behavior in packaging.
- Paints and Resins Industry – Monitoring thermal decomposition, evaluating filler content, and assessing thermal stability of polymers and coatings to ensure durability and performance.
- Food Industry – Analyzing moisture content, fat oxidation, and thermal degradation of ingredients to determine shelf life and quality control in food products.
- Metallurgy Industry – Studying oxidation resistance, weight loss in alloys, and thermal degradation of materials to optimize high-temperature performance and corrosion resistance.
- Pharmaceuticals – Detecting solvent residues, analyzing hydrate forms, and ensuring stability under thermal stress for drug formulations.
- Nanomaterials & Composites – Evaluating filler content, carbon nanotube purity, and thermal degradation of advanced coatings.
- Quality Control – Ensuring batch consistency by comparing mass loss profiles, detecting impurities, and verifying material composition in production
