The differential thermal analyzer investigates the correlation between sample temperature and its diverse physical and chemical properties. Equipped with microcomputer capabilities, the DTA series differential calorimeter enables qualitative analysis of substances, encompassing identification, composition, thermal parameter determination, and purity assessment. It aids in discerning whether thermal effects arise from physical or chemical processes and delves into phenomena such as phase transition, decomposition, combination, resolution, solidification, crystallization, evaporation, and sublimation in substances.

Instrument Feature of DTA Analysis System (DTA)
1.Furnace controlled automatic lifting, positioning accuracy, improved measurement repeatability.
2.Atmosphere control system use the flow controller (MFC), steady flow of gas can automatically switches in the process of experiment, high precision, good repeatability, response speed. (can be customized resistance to all kinds of corrosive gas atmosphere control system).
3.All measurement process automatically, automatic drawing. Special data processing (DTA peak area and heat enthalpy calculation, kinetic parameters calculation, data comparison, many algorithms calculate the activation energy and glass transition temperature and comparison method to measure specific heat, etc.).
4.System to collect samples in the process, can be arbitrary moment screenshot, according to the size of the output signal automatic transformation range.
5.Users can use indium, tin, lead and standard sample on the accuracy of the instrument of temperature, energy correction.
6.The instrument is equipped with a rapid cooling system (the furnace temperature drops from 1550 ℃ to room temperature for ≤ 15 minutes).
7.The user the calculation formula and calculation method, our factory can provide the corresponding software development products.
8.Independent research and development of the constant temperature controller; Constant temperature gas chromatography and mass spectrometry connected head; Constant temperature; Can fully guarantee the tar and various kinds of secondary reaction gas detection.
