Thermogravimetric analysis (TGA) is the mass loss or gain in a sample as a function of temperature and time under controlled atmospheric conditions. More simply, TGA measures the mass lost or gained as a sample is heated according to a predefined program of temperature and time. Traditionally samples are placed into laboratory ovens and muffle furnaces for fixed times and usually at fixed temperatures. Samples are subsequently weighed manually. LabFit’s TGA units with integrated load cells combine drying, ashing and weighing processes. This drastically improves efficiency, precision and accuracy, and sample throughput.

LabFit TGA’s determine data such as such as moisture content, loss or gain of ignition, loss of volatiles, oxidation, pyrolysis, plasticizer loss, and ash content. The TGA’s are suitable for a wide range of materials such as ores, coal, coke, cement, lime, polymers, adhesives, foodstuffs, pharmaceuticals, chemicals, paper, tobacco and organic samples.

LabFit TGA’s are used to analyses samples in accordance with several international standards such as ISO and/or ASTM standards
