Meaning of differential scanning calorimetry in English:

differential scanning calorimetry

See synonyms for differential scanning calorimetry


  • A method of measuring the difference between the amounts of heat needed to increase the temperatures of a sample and a reference when the temperatures of both are changed in step with one another; abbreviated DSC.

    The principle behind differential scanning calorimetry is that when a sample undergoes a physical transformation as the temperature is varied, a different amount of heat will need to flow to it than to the reference to maintain both at equal temperatures. It can be used to measure various characteristic properties of a sample, including physical changes (as crystallization or melting) and chemical ones (as oxidation); it is also used as a quality control procedure.
