Thermal Analysis

Thermal analysis (TA) refers to the method of analyzing the relationship between thermodynamic parameters or physical parameters as a function of temperature. The International Thermal Analysis Association defined thermal analysis in 1977 as “Thermal analysis is a technique for measuring the physical properties of a substance at a programmed temperature, and temperature dependence.” It is a very important analytical test method, which is widely employed in both scientific and industrial domains in its various guises.

The advantages of TA over other analytical methods can be summarized as follows:

  • Various temperature programs can be used to study samples over a wide temperature range
  • Various sample containers or accessories can be used to hold almost any physical forms of the samples (solid, liquid or gel)
  • Need a small amount of samples (0.1 μg-10 mg)
  • The atmosphere around the samples can be standardized
  • The time required to complete the experiment ranges from a few minutes to several hours
