DSC 204 F1 Phoenix® – Differential Scanning Calorimeter. DIFFERENTIAL THERMAL ANALYSIS (DTA) Presented By Mr. Shaise Jacob Faculty Dept. Differential thermal analysis (DTA) is a thermoanalytic technique that is similar to differential scanning calorimetry.In DTA, the material under study and an inert reference are made to undergo identical thermal cycles, (i.e., same cooling or heating programme) while recording any temperature difference between sample and reference. Differential Thermal Analysis (DTA) • Principle: The basic principle involved in DTA is the temperature difference (∆T) between the test sample and an inert reference sample under controlled and identical conditions of heating or cooling is recorded continuously as a function of temperature or time, thus the heat absorbed or emitted by a chemical system is determined. Along with qualitative information, this report include the quantitative analysis of various segments in terms of market share, growth, opportunity analysis, market value, etc. Study of thermal effects observed by differential thermal analysis. for a characterization technique samples size, geometry, sample prep, etc?
