Innovative solutions for thermogravimetric analysis

Since 1987 companies around the globe have trusted IMP to provide them with innovative, quality laboratory equipment and instrumentation.

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature (with constant heating rate), or as a function of time (with constant temperature and/or constant mass loss). TGA can provide information about physical phenomena, such as second-order phase transitions, including vaporisation, sublimation, absorption, adsorption, and desorption. Likewise, TGA can provide information about chemical phenomena including chemisorptions, desolvation (especially dehydration), decomposition, and solid-gas reactions (e.g. oxidation or reduction).


TGA is commonly used to determine selected characteristics of materials that exhibit either mass loss or gain due to decomposition, oxidation, or loss of volatiles (such as moisture). Common applications of TGA are materials characterisation through analysis of characteristic decomposition patterns, studies of degradation mechanisms and reaction kinetics, determination of organic content in a sample, and determination of inorganic (e.g. ash) content in a sample, which may be useful for corroborating predicted material structures or simply used as a chemical analysis.

IMP TGA’s are:

• Suitable for applications such as ores, coal, coke, cement, lime, polymers, adhesives, foodstuffs, pharmaceuticals, chemicals, paper, tobacco and organic samples
• Designed to meet the testing requirements of international standards such as ISO and/or ASTM standards
• All models are efficient, simple, safe, convenient and ergonomic to operate
• Instruments can be controlled from a mobile phone, tablet or any computer

IMP is currently looking for interested parties to distribute their range of TGA’s. If you would be interested, please don’t hesitate to contact them.
