Using Smart Thermal Analysis For Automated Evaluation of TGA, STA and DSG Measurements

AutoEvaluation by NETZSCH is an incredibly useful tool for evaluation of thermoanalytical measurements. Using AutoEvaluation, the entire measurement can be evaluated automatically and autonomously (not via pre-defined macro!), requiring just one mouse click and just one second, saving a lot of valuable time.

Furthermore, evaluations from AutoEvaluation are user-independent. Although the use of AutoEvaluation is most likely for novice users, experts will also find it useful for a second opinion. Whatever the context, AutoEvaluation makes thermal analysis smarter!

Video showing the use of AutoEvaluation (and also Identify):

All manner of processes can be evaluated automatically including: glass transitions, crystallization and melting peaks observed in DSC measurements of polymers. Melting peak evaluation also extends to metals and other, e.g., calibration materials.

For TGA, every significant mass change is evaluated and the DTG curve can be shown including peak temperatures already labeled – all done by AutoEvaluation in just one click. AutoEvaluation can even be incorporated into measurement methods: this allows evaluations to be performed automatically as soon as the measurement is finished!

Video highlighting the new functions “Endo and Exo” (especially for STA):

“Endo- and Exo Effects” is a new function in AutoEvaluation that analyses DSC curves and automatically evaluates any endothermic or exothermic effects. This is completely independent of the sample material and independent of the instrument used (NETZSCH DSC 2xx, DSC 404 or STA 449).

Adaptability of AutoEvaluation

AutoEvaluation is extremely versatile, with multiple functions like “Polymer” or “Endo and Exo”, letting it adapt to a particular application. The Settings feature is useful for customizing the readout, allowing a user to choose which evaluations done by AutoEvaluation should be displayed, and which properties of these evaluations like peak area or onset temperature should be shown. Finally, it is important to mention that any result gained through AutoEvaluation can be revised by the user – if desired.
