HCT-1 Microcomputer Differential Thermal Balance Introduction
Comprehensive thermal analysis combines thermogravimetric analysis TG with differential thermal analysis DTA or differential scanning calorimetry DSC. The same sample can be used to obtain thermogravimetric and differential thermal information in the same measurement.
HCT-1 microcomputer differential thermal balance (integrated thermal analyzer) mainly measures physical and chemical changes related to heat, such as the melting point, heat of melting, heat of crystallization and crystallization, heat of phase change reaction , Thermal stability (oxidation induction period), glass transition temperature, adsorption and desorption, analysis of component content, decomposition, compounding, dehydration, additives and other changes. Features
Heat flow DSC data acquisition method, draw the curve of energy and temperature.
Users can use standard samples to calibrate temperature, energy and thermogravimetric accuracy.
The atmosphere control system uses a mass flow controller. The three-way voltage-stabilizing and steady-flowing gas can be automatically switched during the experiment, with high accuracy, repeatability and response.
Fast speed (atmosphere control system can be customized to resist various corrosive gases).
It can meet all requirements from micro-samples to high-dose samples (change the support rod, the maximum sample can reach 5g). It can meet the test requirements of various samples under different conditions.
All measurement processes are completed automatically, automatic drawing, and rich software functions can complete conventional data processing of DTA, TG, DTG, DDTG; special data processing (DTA peak area, enthalpy calculation, kinetic parameter calculation, data comparison, multiple algorithm calculations Activation energy, glass transition temperature, specific method for specific heat, etc.).
During the sample collection process, the system can take screenshots at any time and automatically change the range according to the output signal size.
Large-screen liquid crystal display, real-time display of the instrument status and data, two sets of temperature measuring thermocouples, one set of real-time display furnace temperature (regardless of whether the furnace is working or not), and another set of thermocouples display the sample temperature during work.
The user gives the calculation formula or calculation method, and our factory can provide the corresponding software to develop the product in time.
Independently developed constant temperature controller; constant temperature gas chromatography, mass spectrometry connector; constant temperature zone; can fully guarantee the secondary detection of tar and various reaction gases. Technical Parameters
