Most simultaneous thermal analyzers use a combination of Thermo gravimetric analysis (TGA) and differential scanning calorimetry (DSC) to do their analysis (STAs). With a combinatorial approach, one instrument can collect multiple types of information at the same time. For example, DSC can measure how a material reacts to stress, and TGA can measure how its mass changes with temperature and time. Both can work together because the test conditions are the same for both. Among other things, simultaneous analyzers can be used to test polymers, food, nanomaterial, metals, and oil. When buying a TGA DSC Simultaneous Thermal Analyzer, it’s important to think about the temperature range that can be reached and how the temperature is controlled, the measuring range and sensitivity for mass analysis, and the way pressure is made, and the maximum load.


Applications for TGA-DSC:

We show how a simultaneous TGA/DSC thermal analyzer can be used as a high-throughput reactor system to quickly, reliably, and repeatedly measure the heat of reaction and, by extension, the catalytic activity of heterogeneous catalysts after calibration. By connecting the analyzer’s gas outlet to a mass spectrometer with a heated capillary, more information can be gathered. The oxidation of carbon monoxide with synthetic air was chosen as a test reaction. Hopcalite and a few transitions and noble metals were used as catalysts. With the setup shown, about 70 catalysts can be tested quickly and in order every day.
