2. 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 . In differential thermal analysis (DTA), the difference in temperature between the sample and a thermally inert reference material is measured as a function of temperature (usually the sample temperature). Any transition that the sample undergoes results in the liberation or absorption of energy by the sample with a corresponding deviation of .manufacturing or laboratory setting. A thermal investigation can provide information about particle and coating composition, crystallinity, and formation kinetics. Thermogravimetric analysis, calorimetry and differential scanning calorimetry are the most common thermal analysis methods utilized for nanoparticle TGAs are often combined with differential thermal analysis (DTA). While the TGA measurement is used for determining when a material loses mass due to thermal degradation, DTA can also capture events where the mass is not lost, such as phase changes and chemical reactions. Consider an unknown alloy that is heated in a TGA/DTA instrument.
Figure \(\PageIndex{1}\): Illustration showing typical experimental curves for a differential thermal analysis (DTA) or a differential scanning calorimetry analysis (DSC) for a polymeric material. For a DTA analysis, the difference in temperature, \(\Delta T\), is measured and for a DSC analysis, the flow of heat is measured.
Features: Differential thermal curve can describe the relationship of the temperature difference T changes with the temperature or time between the sample and the reference material. Technical parameters:--T emperature range: room temperature ~1150ºC; --D ifferential thermal range: 0~±2000µV; --P recision of DTA: ±0.1µV.
Due to the large amount of information provided, differential thermal analysis is the most widely used thermal analysis method. The Linseis high-temperature DTAPT 1600 enables the highest calorimetric sensitivity, a short time constant and a condensation-free sample chamber in a single device. Our concept guarantees an extremely high resolution with simultaneous baseline .
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.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 Thermal Differential Scanning Calorimetry Instrumentation Analysis Instrument Machine, Find Details and Price about Differential Scanning Calorimetry Price Differential Thermal Analyzer from DSC Thermal Differential Scanning Calorimetry Instrumentation Analysis Instrument Machine - Jinan Cyeeyo Instruments Co., Ltd.
