Differential Thermal Analyzer (DTA Analyzer)

A differential thermal analyzer, also commonly referred to as a DTA analyzer, is used in analytical chemistry to identify and quantitatively analyze the chemical compositions of a sample by heating the sample and recording the behavior of the sample, which includes the temperature and heat flow between phase transition (i.e. melting point, crystallization, etc.) as a sample will undergo reactions and phase changes as it is heated. This results in the absorption or emission of heat. These exothermic or endothermic changes in the sample can be detected relative to a reference. Differential thermal analyzers are widely used for metallurgy, semiconductors, pharmaceuticals, food testing, cement chemistry, and environmental research.
