Gas evolution as an artefact in differential scanning calorimetry
- 31 Downloads
With CuSO4·5H2O as test system, it is demonstrated that the evolution of a gaseous product with thermal conductivity much lower than that of the purge gas in differential scanning calorimetry, leads to artefacts in the form of intense exotherms. This is due to a reduction of the heat flow from the sample to the environment.
