Thermogravimetric (TG) measurements are a well established method in materials science, physics and chemistry. The continuous weight measurement of a sample while exposing it to a temperature program under controlled atmospheric conditions provides important information about chemical reactions and structural changes of the sample material.
As with all other Rubotherm gravimetric instruments our thermogravimetric analyzers are also equipped with the unique magnetic suspension balance. As a result of that, Rubotherm¡¯s DynTHERM line of TGA instruments can measure under conditions where all other instruments fail: TG measurements using corrosive or toxic atmospheres, in vapor and/or under high pressure conditions. Additionally, the Magnetic Suspension Balance allows recording and correction of the baseline drift and recalibrating of the balance during long term measurements – thus, providing the extraordinary long term accuracy and stability typical for our instruments.
The DynTHERM line of instruments is divided in low, medium and high pressure analyzers. Furthermore, the modular setup makes it possible to upgrade or re-arrange the setup for other measuring purposes. Depending on the resolution the sample is placed in a sample crucible on top of a toploading balance (0.01 µg ¡¦ 0.1 µg) or suspended by means of a hang down wire (1 µg ¡¦ 10 µg)
The DynTHERM instruments can be equipped with different versions of the Magnetic Suspension Balance with the following specifications
