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.

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.

Differential scanning calorimetry and temperature-modulated differential scanning calorimetry: an extension to lower temperatures

High Temperatures-High Pressures, 2000
Temperature-modulated differential scanning calorimetry (TMDSC) has become a versatile technique for determining the specific heat (c p ) properties of condensed matter, but commercial instruments do not allow TMDSC measurements below 130 K. A top-loading cryostat incorporated within a commercial TMDSC instrument is presented, which allows c p ...

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 ...

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.

Biochemical Applications of Differential Scanning Calorimetry

Annual Review of Physical Chemistry, 1987
Differential scanning calorimetry (DSC) and the closely related differential thermal analysis (DTA) have been widely employed during the last several decades in the thermodynamic study of processes that are initiated by either an increase or a decrease in temperature. This review focuses on biochemical applications of DSC.

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 ...

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

Compatibility of Differential Scanning Calorimetry and ac Calorimetry

Japanese Journal of Applied Physics, 1994
In the simultaneous measurement of heat capacity by differential scanning calorimetry and ac calorimetry using the same apparatus with ac temperature modulation superposed on a linear temperature ramp, the principle of measurement by ac calorimetry is not sufficiently understood yet.
