Facility Description
Heat Flux DSC
A technique in which the sample and reference crucible are heated uniformly (under the same conditions) with a definite amount of heat. The difference in temperature between the sample and the reference material gives the heat capacity of the sample and is measured as a function of time and temperature.
DSC is a thermal analytical technique that looks at how a material’s heat capacity (Cp) is changed by temperature. It measures the amount of heat released or absorbed by a material and hence DSC enables the measurements of the transition such as the glass transition, melting, and crystallization.

Sample Preparation, User Instructions and Precautionary Measures
- At least 30-40 mg of sample should be submitted.
- Sample size should be < 5mm in diameter and < 2.5mm in thickness.
- Samples containing halogens should not be sent and will not be accepted for analysis.
