A Brief Note on Thermal Analysis
Thermal analysis is a specialized segment of science that deals with the study of properties of different materials as they change with fluctuation in temperature. There are several types of analysis methods that are popular in the present times. For instance, ‘Dielectric thermal analysis’ or DEA method is used for measuring dielectric permittivity while ‘Differential thermal analysis’ or DTA measures temperature difference. ‘Thermo optical analysis’, better known as TOA, is used for analysing optical properties. Another popular thermal analysis methodology, Simulation Thermal Analysis or STA refers to application of ‘Thermogravimetry’ as well as DSC or ‘Differential Scanning Calorimetry’ in simultaneous manner.Â
    In simple terms thermal analysis process is widely used in order to indicate a specialized branch of study that analyses heat transfer process in different structures. Know the importance of this analysis in studying different materials or properties:
For analyzing pharmaceutical materials:
This type of analytical method is used for determining characteristics of different pharmaceutical elements. Differential Scanning Calorimetric method alone and also in amalgamation with hot staging microscopic process differentiates between several polymorphic structures. Making use of diverse heating rates, it also investigates transformation that usually occurs during transformation of polymorphic elements. It also helps in determining purity of polymorphic components. TGA methodology also is used for measuring residual solvents as well as moisture and also may be widely used for determining the solubility of different pharmaceutical elements in solvents. In fact this analytical study of different pharmaceutical materials forms the biggest part of thermal analysis application.Â
For analyzing different metals
In production of different types of metals like ductile iron, copper alloys, steel, silver etc, this type of heat analysis plays a vital role. For example good quality liquid metal is effectively removed from furnace and then placed inside a cup where thermocouple is embedded. After that temperature is nicely monitored and also different types of phase diagrams are noted. Specifically speaking thermal analysis of metals is done effectively in case of metals.
