Thermal analysis is an analytical method to study the relationship between physical and chemical changes and temperature of materials. This article summarizes application of thermal analysis technology in research field of traditional Chinese medicine. 1. Classification of Methods of Thermal Analysis Technology There are various types of thermal analysis methods, among which differential thermal analysis (DTA), thermogravimetry (TG) and differential scanning calorimetry (DSC) are the most widely used in study of traditional Chinese medicine, and selection of thermal analysis samples pan is relatively stable. 1.1 Differential Thermal Analysis (DTA) The method of measuring the temperature difference between the test object and the reference object is called Differential Thermal Analysis (DTA). 1.2 Differential Scanning Calorimetry (DSC) DSC is heating up the sample and reference material, and measuring their difference of heat absorbed or released during the h...
