Overview

thermal analysis


Show Summary Details

Quick Reference

A technique for chemical analysis and the investigation of the products formed by heating a substance. In differential thermal analysis (DTA) a sample is heated, usually in an inert atmosphere, and a plot of weight against temperature made. In differential scanning calorimetry (DSC) heat is added to or removed from a sample electrically as the temperature is increased, thus allowing the enthalpy changes due to thermal decomposition to be studied.

Subjects: Chemistry.
