Smart Thermal Analysis (Part I): Automatic Evaluation of DSC, TGA and STA Measurements

Smart Thermal Analysis (Part I): Automatic Evaluation of DSC, TGA and STA Measurements

AutoEvaluation by NETZSCH is a very helpful tool for evaluation of thermoanalytical measurements. The entire measurement is evaluated by AutoEvaluation automatically and autonomously (not via pre-defined macro!) – with only one mouse click – and just within a second. AutoEvaluation is available for DSC, TGA and now also for STA measurements. Furthermore, the adaptability of AutoEvaluation is adressed.

AutoEvaluation by NETZSCH is a very helpful tool for evaluation of thermoanalytical measurements. The entire measurement is evaluated by AutoEvaluation automatically and autonomously (not via pre-defined macro!) – with only one mouseclick – and just within a second. This saves a lot of valuable time! Moreover, evaluations from AutoEvaluation are user-independent. AutoEvaluation is clearly supporting beginners but also gives a second opinion for experts. In any case, AutoEvaluation makes thermal analysis smarter!

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

Glass transitions, crystallization and melting peaks observed in DSC measurements of polymers are evaluated automatically. Furthermore, melting peaks of metals and other, e.g., calibration materials can be evaluated. In case of TGA, all significant mass changes are evaluated and the DTG curve can be shown including peak temperatures already labeled –  everything with one click by AutoEvaluation. And AutoEvaluation can even be incorporated into measurement methods: In this case, the evaluations are done automatically right after the measurement finished!

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

The new function for AutoEvaluation, called “Endo- and Exo Effects”, automatically evaluates any endothermic or exothermic effects occurring in DSC curves. Independent of the sample material and independent of the instrument used (NETZSCH DSC 2xx, DSC 404 or STA 449).

Adaptability of AutoEvaluation:

Since several functions like “Polymer” or “Endo and Exo” exist, AutoEvaluation can be adapted to the particular application. Which evaluations done by AutoEvaluation should be displayed? And which properties of these evaluations (like peak area, onset temperature, …) should be shown? All this can be customized in Settings. Last but not least, the results of AutoEvaluation could be revised by the user – if desired.

  1. We have DSC – Polyma 214 in our lab since 2015. We are producing Polyester and Vinylester as well as Saturated Polyester resin from last 25 years. We are unable to detect exact Tg value from the test, every time the software detects multiple Tg values at different scale. The Netzsch representative always unable to sort out the issue. we request you to please suggest and guide us.
    Thanks and regards,

    • Dear Mehboob Shabhai,

      please send me such a doubtful measurement file and we will analyze what the problem is.

      Thank you and best regards,

  2. Dear Dr. Alexander Schindler,
    Is this software compatible with TA instruments?

    Thank you,

    • Dear Allison Mundinger,

      this AutoEvaluation-Software is within Proteus Analysis by NETZSCH. It is optimized and tested for NETZSCH data. We are working on a solution where users of Proteus Analysis can apply AutoEvaluation on any ASCII-imported data. If you like, please send me some ASCII-exported data and I will try how the function works.

      Thank you and best regards,
