About analysis
DSC analysis: DSC differential scanning calorimeter analysis
DSC analysis is used to investigate thermal behavior. This analysis can determine the temperature and heat of phase change (melting, change in crystal structure, etc.) and chemical changes (decomposition, oxidation, etc.). DSC analysis, like DTA, is an analysis to determine the physical-thermal behavior of materials and can be used to obtain the physical properties of the material such as melting temperature, evaporation temperature and other phase changes of materials such as crystal deformation temperature or as a chemical-thermal analysis Obtain the decomposition or oxidation temperature of the material
The advantage of DSC analysis over DTA analysis is that in this analysis, in addition to the temperature of transformations or reactions, the heat generated or absorbed can also be determined. In the DSC test, a comparison between two samples of the rate of transformations or chemical changes can also be qualitatively compared

Specifications of DSC analysis sample
Sample weight should be at least 20 mg and at most 0.1 g
Non-powdered samples should not be larger than 2 mm
The sample should not contain compounds that can explode or produce strong gas, so the overall chemical composition of the sample should be known
The heating rate, maximum temperature and sample composition must be specified by the applicant
The analysis price depends on the specified temperature range and the cream rate can vary
The device software does not have the ability to determine the Tg point and other points in this test and applicants must obtain it themselves
Results of analysis and interpretation of DSC analysis
The analysis results are presented as a PDF file and an EXCEL file. The PDF file shows the test result in the form of a graph with test specifications. The EXCEL file contains device specifications, test conditions and point-to-point data related to the analysis chart. Using this point-to-point data, the analysis chart can be drawn in different software and the diagram and thermal behavior of the material can be studied
