Domestic thermal analysis instrument professional manufacturer
Dedicated to thermal analysis instrument for more than 20 years
Instrument introduction
Comprehensive thermal analysis combines TG with DTA or differential scanning calorimetry (DSC) to obtain TG and DSC information simultaneously in the same measurement using the same sample.
Instrument use
It mainly measures the physical and chemical changes related to heat, such as the melting point of substances, melting heat, crystallization and crystallization heat, phase transition reaction heat, thermal stability (oxidation induction period), glass transition temperature, adsorption and desorption, composition content analysis, decomposition, combination, dehydration, additives and other changes.
Instrument characteristics
The curve of energy and temperature is drawn by DSC data acquisition.
The user can adjust the temperature, energy and thermogravimetric accuracy by himself using standard samples.
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).
From small samples to large doses of samples can be satisfied (change the support rod can achieve 0 ~ 5g adjustable). It can meet the test requirements of various samples under different conditions.
The whole measurement process is completed automatically, and the drawing is automatic. The rich software functions can complete the routine data processing of DTA, TG, DTG and DDTG. 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.
Large-screen LCD display, real-time display of instrument status and data, two sets of temperature measurement couples, one set of couples real-time display furnace temperature (whether the heating furnace is working or not) and the other set of couples display sample temperature at work.
The user gives the calculation formula or calculation method, our factory can provide the corresponding software development products in time.
Self-developed thermostat controller; Constant temperature gas chromatography, mass spectrometry connection head; Constant temperature zone; It can fully ensure the secondary detection of tar and various reaction gases.
