HQR-1/2/3/4 Differential Thermal Analyzer (DTA)

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. DTA analysis 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 Differential Thermal Analyzer (DTA)

01

The furnace is automatically raised and lowered with accurate positioning, which improves the repeatability of measurement.

02

Atmosphere control system use the flow controller (MFC), which can automatically switch the gas with a stable flow rate in the process of experiment, with high precision, good repeatability and fast response. (The atmosphere control system resistant to various corrosive gases can be customized.)

03

All measurement processes is automatically completed and plotted. Special data processing includes DTA peak area and thermal enthalpy calculation, kinetic parameter calculation, data comparison, multiple algorithms to calculate activation energy and glass transition temperature, comparison method to measure specific heat, etc.

04

In the process of collecting samples, the system can take screenshots at any time and automatically change the range according to the size of the output signal.

05

Users can use standard samples such as indium, tin, and lead to calibrate the thermogravimetric differential thermal analysis instrument by temperature and energy.

06

The TG DTA analysis instrument is equipped with a rapid cooling system. (The furnace temperature drops from 1550 ℃ to room temperature for ≤ 15 minutes).

07

The user provides the calculation formula and method, and Henven, a leading TGA thermogravimetric analyzer supplier, can provide the corresponding software development products.

08

The independently developed constant temperature controller, along with the constant temperature gas chromatography-mass spectrometry connector and constant temperature belt, which can fully ensure the secondary detection of the tar and various reaction gases.
