Differential Scanning Calorimeter

Instrument Introduction

Instrument for measuring the temperature difference between a substance and a reference material, as a function of temperature, under programmed temperature control.

Instrument Usage

Primarily measures physical and chemical changes related to heat, such as the melting point, heat of fusion, crystallization and its heat, phase change reaction heat, thermal stability (oxidation induction time), glass transition temperature, and other variations.

Instrument Features

The LCD screen displays the furnace temperature and sample temperature, as well as the gas circuit status in real-time.

Oxidation induction period test analysis software available.

At any temperature point within the heating range, it can maintain a constant temperature for 72 hours.

Features crystallization kinetics calculation and stepwise cooling curve plotting functions.

An integrated instrument combining electrical machinery and atmosphere control, reducing signal loss and interference.

The atmosphere control system utilizes a mass flow controller, featuring two lines of stable pressure and flow gases that can automatically switch during the experiment. It boasts high precision, excellent repeatability, and rapid response time (customizable atmosphere control systems resistant to various corrosive gases available).

The entire measurement process is fully automated, with automatic plotting. Software functionalities enable routine DTA data processing; special data handling includes DTA peak area calculation, enthalpy computation, kinetic parameter calculation, data comparison, various algorithm-based activation energy, glass transition temperature, and comparative measurement of specific heat, etc.

During the system's sampling process, screenshots can be taken at any time, and the range will automatically adjust based on the output signal size.

Users can calibrate the instrument's accuracy in temperature and energy using standard samples such as indium, tin, and lead.

Large-screen LCD display, real-time showing the status and data of the instrument, two sets of thermocouples, one set displaying the furnace temperature in real-time (regardless of whether the heating furnace is in operation), and the other set showing the sample temperature during operation.

Customers provide the formula or calculation method, and our company can promptly provide the corresponding software development products.

Self-developed constant-temperature controllers, constant-temperature gas chromatography-mass spectrometry interfaces, and constant-temperature belts ensure thorough secondary testing of tar and various reaction gases.
