Simultaneous Thermal Analysis (STA) is a well-established analytical method that generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Thermal Analysis (DTA) or Differential Scanning Calorimetry (DSC) to a single sample in the same instrument. The DTA/DSC signal shows caloric effects due to mass loss or gain and structural phase transformations where there is usually no mass loss.
Modern, state-of-the art STA instruments offer high flexibility, user-friendly software and a wide operating temperature range spanning −150…2400 °C ensuring almost any material can be covered. Another advantage compared to stand-alone TGA instruments is the possibility of measuring samples with significantly larger volume and mass. Sample sizes approaching 5ml and several grams are possible allowing detection of tiny effects in the ppm range.
In the first part of the webinar series, we will discuss the measuring principles used in Simultaneous Thermal Analysis (DTA, DSC, TGA) and the different material properties that can be measured. We will introduce NETZSCH’s state-of-the-art STA instrumentation and show a series of application examples from different fields including building materials, polymers, batteries and pharmaceuticals.
Achieving a reliable, meaningful result from an STA experiment requires careful sample preparation and the selection of suitable measurement parameters including temperature programme, test atmosphere/s and sample holders. The instrument calibration also has a major influence on the quality of the measurement data. In this webinar we will discuss the most important influencing factors for STA measurements and show how to setup up a measurement via a live demonstration with the NETZSCH Proteus Software.
Analysis and interpretation of measurement curves is usually the final step after completing an STA measurement. In part 3, we will show how to evaluate STA measurements in the NETZSCH Proteus Software including a live demonstration of NETZSCH’s unique one-click AutoEvaluation software feature. We will conclude the webinar series by presenting a selection of special application examples and answering some FAQ’s from the earlier webinars.
