  • Thermo Gravimetric Analysis (TGA)

    Thermogravimetric analysis is a technique to measure the relationship between mass and temperature or time under programmed temperature control. By analyzing the thermogravimetric curve, we can know the information related to the quality, such as the composition, thermal stability, thermal decomposition. The application of thermogravimetric analysis is mainly in metal alloy, geology, polymer material research, drug research and so on. As a professional reliability third-party testing organization, T,C&A Lab can perform TGA service for raw materials and finished products according to ISO, ASTM standards and industry requirements. Welcome to contact our experts for consultation.

    Why do TGA testing

    • Study physical phenomena such as melting, evaporation, sublimation and adsorption.
    • Study chemical phenomena such as dehydration, dissociation, oxidation and reduction of substances.

    Analysis and testing capabilities of TGA

    • Thermal decomposition of inorganic, organic and polymer
    • The corrosion process of metals by various gases at high temperatures
    • Calcination and smelting of minerals
    • Distillation and vaporization of liquids
    • Pyrolysis process of coal, oil and wood
    • Determination of moisture content, volatile matter and ash content
    • Sublimation process
    • Dehydration and moisture absorption
    • Study on explosive materials
    • Study on reaction kinetics
    • Discovery of new compounds
    • Adsorption and desorption
    • Determination of catalytic activity
    • Determination of surface area
    • Study on oxidation stability and reduction stability
    • Study on the reaction mechanism

    Our case studies include, but are not limited to

    • Determination of metal and gas reaction

    The reaction between metal and gas is a gas-solid phase reaction. Thermogravimetric analysis can be used to determine the relationship between mass change and temperature in the reaction process, and it can be used for kinetic analysis of reaction volume.

    • Application in geology

    Mineral identification: The thermogravimetric curve of minerals will show different characteristics due to their different composition and structure. The minerals can be identified by comparing the starting temperature, peak temperature and peak area with known mineral characteristic curves.

    • Quantitative analysis

    The quality of the sample changes under the programmed temperature, and the composition of the sample can be quantitatively analyzed by using this phenomenon.

    • Application in polymer materials

    Evaluate the thermal stability of polyolefins, polyhaloolefins, oxygen-containing polymers, heteroaromatic polymers, monomers, and elastomeric polymer materials.

    Standards we test to

    • ASTM D6370-99, ASTM D3850, ASTM D6375-09, ASTM E2105, ASTM D6559, ASTM D6558, ASTM D7582, ASTM D8339
    • ISO 247, ISO 12989, ISO 12988, ISO/TS 11308, ISO/DTS 23690, ISO 248, ISO 22821, ISO 9924
