How Does Thermal Analysis Work?

Thermal Analysis

To know how thermal analysis works it is important that we understand what thermal analysis is and where it is used. Thermal Analysis influences that part of science that deals with materials. There are almost 11 known types of thermal analysis. Depending on the situation and the material that is about to undergo the test these thermal analyses are classified. In the process of thermal analysis, the administer makes an effort to find how a material reacts at different temperatures. In simple terms change in material in correspondence with the change in temperature. This is the simple science behind the thermal analysis.

Thermal Analysis

History and Scope of Thermal Analysis:

  • It is quite interesting to note that thermal analysis came into existence during the BC days. This is because most of the changes that natural sciences dealt with were with regard to fire. So they regarded fire as the basic matter that propelled change within two physical quantities.
  • Keeping the above point in mind, the sciences that followed also employed fire as the considered it as the general analyzer of matter. However, they kept redefining the word fire with words like heat and temperature.
  • Thermal Analysis is primarily used in the pharmaceutical industry. So it has to be either a chemist or a pharmacist who will possibly be handling the thermal analysis procedures.
  • Usage of thermal analysis is widely used in the chemical industry. This is because the change in the reaction between two materials can be monitored quickly be a chemist only with the fluctuation in temperature.
  • Almost all the studies carried out in the purview of thermal analysis can be classified into three major heads. They are Mass, Temperature or other parameters such as dimensions, etc. Depending what head the materials fall into, the method of thermal analysis is chosen.
  • There is also a concept called Simultaneous Thermal Analysis where the method enables the application of two processes such as a thermal analysis and a differential scanning calorimetry on the same material, at the same time and also in the same instrument.
  • The common application of thermal analysis is found in pharmaceutical materials, polymer, metal, food and printed circuit boards

Now that you have gotten a basic idea of what is thermal analysis, let us see how the process works:

Process of thermal analysis:

  • Thermal Analysis begins with finding the right method that has to be applied to the material that is undergoing the test.
  • Once the suitable method is found, the next thing is to apply the same onto the materials. A set of tools and instruments are required to carry out the process. Once you have the things set, you can get to the process of thermal analysis.
  • At varying degrees of heat, the material is tested, and the corresponding changes are recorded along with the results. The point at which the material is found to give the required result is what we find through the thermal analysis.
