Measure Any Sample with Precision

Measure-Any-Sample-with-PrecisionThermogravimetry (TGA) is a technique that measures the change in weight of a sample as it is heated, cooled or held at constant temperature. Its main use is to characterise materials with regard to their composition. Application areas include plastics, elastomers and thermosets, mineral compounds and ceramics.

Mettler Toledo launched the TGA 1, which is a sensitive analyser that offers easier characterisation of plastics, elastomers, thermosets and other materials. It measures up to 50 million resolution points continuously, down to 0.1µg for a 5g sample weight. Additionally, with no weight range change required when switching between sample sizes, a wide variety of sample types can be measured in succession.

The heart of the TGA 1 is the Mettler Toledo balance cell. Internal calibration ring weights built into the balances help manufacturers characterise materials with a high degree of accuracy. This provides the information required to ensure heat and moisture-sensitive materials will perform as expected in their final context.

Its modular design increases flexibility and ease of use. It has a variety of furnace/crucible sizes that help broaden the TGA 1’s application range. It can handle temperatures from ambient to 1100 ̊C, which provides complete thermal analysis in a single step. Results are analysed using STAR® software. A horizontal furnace minimises turbulence caused by thermal buoyancy and purge gas, while a gastight cell that can be purged with a defined gas atmosphere offers quality results.
