Dierential Thermal Analysis 12.1 INTRODUCTION Dierential thermal analysis (DTA) is complementary to thermogravimetric analysis (TGA). However, DTA is much more versatile. The data obtained from DTA are of more fundamental in nature. In DTA, a smaple and a reference material are heated (or cooled) at a linear heating rate.

DSC Differential Scanning Calorimeter – The DSC Thermal Analyzer measures the energy absorbed or released from a sample as a function of time or a temperature. This analyzer is useful to make the measurements for melting points, heats of reaction, glass transition, heat capacity and purity determination. The fundamentals of the widest-spread methods of thermal analysis including a short excursion into differential scanning calorimetry are presented. Five practical examples illustrate the experimental approach for the measurement design .View Thermal Analyzers Applications Request a Quote.

Differential thermal analysis (DTA) and differential scanning calorimetry (DSC) 4.1 Classical DTA [1,2] DT A is the simplest and most widely used thermal analysis technique. The difference in temperature, llT, between the sample and a reference material is recorded while both are subjected to the same heating programme. In 'classical'The “DTA” refers to differential thermal analysis. The DTA technique measures the difference between the sample temperature (T s) and the temperature of a reference (T r).). A plot of T s – T R over a programmed temperature range will show a series of peaks or step changes that map the temperatures where thermal events occur. However, the amount of heat absorbed or .Stability of the DTA signal. Previous TG/DTA analyzers enclosed specimens in the heating furnace, preventing observation of sample status. Phenomena occurring in the sample could only be assessed through TG signals (changes in mass) and DTA signals (differential thermal changes), and when assessment was difficult, phenomena could only be inferred.Differential Thermal Analyzer (DTA) uses a two-pan system to measure the heat flux difference between an empty pan (or one with a reference material) against the temperature of a sample of specific weight.
