Interested in DSC Instrumentation? DSC, in essence, measures the amount of energy released or absorbed by the sample in question when it is heated and cooled. The result of a DSC experiment is a curve of heat flux versus temperature or versus time. The information gathered can even be enhanced by coupling … Watson and M.J. O'Neill in 1962, and introduced commercially at the 1963 Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. This technique can be used for both substances and chemical reactions. • In DSC, influence of sample properties on the area of the peak is comparatively lower than in DTA. -180°C to 700°C Measuring Range: All rights reserved. The test conditions are perfectly identical for the TGA and DSC signals (same atmosphere, gas flow rate, vapor pressure of the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Thermo mechanical analysis (TMA): deformations and dimension Dilatometry (DIL): volume Evolved gas analysis (EGA): gaseous decomposition products Often different properties may be measured at the same time: TGA-DTA, TGA-EGA Figure 1 DSC Scan of Polyethylene Terephthalate: Heat Flow versus Temperature. Both cells are heated with a constant heat flux, Q, using a single Soon after World War II ended, Japanese scientists developed thermoanalytical instruments that controlled and recorded the experiments automatically [1].
