Innovation application: Differential Scanning Calorimetry

Title Differential Scanning Calorimetry
Abstract

Differential scanning analysis is proposed. Differential scanning calorimetry is a widely used thermal analysis technique. Enthalpy changes in samples due to changes in their physical and chemical properties as a function of temperature or time are measured.

Keywords DSC, differential scanning analysis, calorimetric properties, crystallinity degree of polymers

Description of the technology

Differentia scanning calorimetry measures the difference between the heat flows from the sample and reference sides of a sensor as a function of temperature or time. Differential scanning analysis is proposed in the temperature range from -90oC to +450oC in inert or oxidative environment by using equipment DSC 1 (Mettler Toledo).
