Modeling differential scanning calorimetry

Thermochimica Acta, 1990
Abstract The present study is a unified mathematical approach to the analysis of DSC data. It addresses the baseline correction to the DSC record as well as the solutions of DSC curves of single or multiple, physical and chemical transformations. In this study, previous results in the pertinent literature become particular solutions of the general ...

Pressure differential scanning calorimetry

Thermochimica Acta, 1970
Abstract A system is described for obtaining differential scanning calorimetry (DSC) data under reduced (to 10 microns) or elevated (to 1000 psi) pressure. Applications illustrating vapor—liquid equilibrium, competitive reactions, relative oxidative stability and pressure induced reactions are discussed.

Differential Scanning Calorimetry

2019
Differential scanning calorimetry (DSC) is a thermal analysis technique which involves the measurement of temperature difference between the sample and the reference material as a function of the temperature while sample and reference both are subjected to a controlled temperature program.

Polymorphism by differential scanning calorimetry

Thermochimica Acta, 1994
Abstract After a basic introduction to polymorphism the most useful methods of detection of polymorphism are cited. A selection of typical DSC curves illustrates monotropic and enantiotropic solid—solid transition, allotropy, metastable—stable transition through the liquid state, pseudopolymorphic transition and mesophase transition. In addition, the

Modulated differential scanning calorimetry

Thermochimica Acta, 1994
Abstract Modulated differential scanning calorimetry (MDSC) is a recently developed extension of DSC that adds a new dimension to the conventional approach. The usually linear temperature programme is modulated by a small perturbation, in this case a sine wave, and a mathematical treatment is applied to the resultant data to deconvolute the sample ...

Differential Scanning Calorimetry

1992
In spite of the fact that there are so many differences between the gas chromatography technique and calorimetry, it may be of interest to compare these two techniques, at least for a while.

Modulated differential scanning calorimetry

Journal of Thermal Analysis, 1993
Modulated DSCTM (MDSC) is a new, patent-pending extension to conventional DSC which provides information about the reversing and nonreversing characteristics of thermal events, as well as the ability to directly measure heat capacity. This additional information aids interpretation and allows unique insights into the structure and behaviour of ...
