Instrument introduction

An instrument for measuring the temperature difference between a substance and a reference substance as a function of temperature under programmed temperature control.

Instrument use

It mainly measures the physical and chemical changes related to heat, such as the melting point of a substance, the heat of melting, the heat of crystallization and crystallization, the heat of phase transition reaction, the thermal stability (oxidation induction period), the glass transition temperature and so on.

Instrument characteristics

Integrated instrument with capacitors and atmosphere control to reduce signal loss and interference.

The atmosphere control system adopts the mass flow controller, and the two channels of stable pressure and steady flow gas can be automatically switched during the experiment, with high precision, good repeatability and fast response speed (the atmosphere control system can be customized to resist various corrosive gases).

The whole measurement process is completed automatically, and the drawing is automatic, and the DTA routine data processing can be completed by using the software function. Special data processing (DTA peak area, enthalpy calculation, kinetic parameter calculation, data comparison, multiple algorithms to calculate activation energy, glass transition temperature, comparative method to measure specific heat, etc.).

In the process of sample collection, the system can take a screenshot at any time and automatically change the range according to the output signal size.

Users can use indium, tin, lead and other standard samples to correct the accuracy of the temperature and energy of the instrument.

Large screen LCD display, real-time display of instrument status and data, two sets of temperature measurement couples, one set of electric couple real-time display furnace temperature (whether the heating furnace is working or not), the other set of electric couple display sample temperature at work.

The user gives the calculation formula or calculation method, our company can provide the corresponding software development products in time.

Self-developed constant temperature controller, constant temperature gas chromatography, mass spectrometry connection head, constant temperature belt, can fully ensure the tar and various reaction gas secondary detection.
