HWD-500 high-dose thermal balance Introduction
HWD-500 high-dose thermal balance is used to analyze the phase change, decomposition, combination, dehydration, adsorption, analysis, solidification, sublimation, evaporation, mass change and other phenomena of large-dose substances.
HWD-500 high-dose thermal balance is mainly used to detect and analyze the phase change, decomposition, combination, dehydration, adsorption, analysis, solidification, sublimation, evaporation, mass change and other phenomena of large-dose substances. This instrument can complete the chemical reaction kinetics research of cracking and gasification of coal, biomass and other materials. The sample can also be protected by the atmosphere according to user requirements. Vacuum can be evacuated to a vacuum of 0.1Mpa. Features
Analysis of phase change, decomposition, combination, dehydration, adsorption, analysis, solidification, sublimation, evaporation, mass change and other phenomena of large-dose substances.
The furnace body can be controlled to rise and fall automatically. After the sample is put in, all operating software controls are completed automatically.
The instrument is equipped with a trace water vapor generating device, which can produce saturated water vapor. The volume is from 01 ml to 1000 ml per minute with an accuracy of 0.01 ml per minute.
Users can use standard samples to perform temperature and thermogravimetric corrections.
Different crucibles can be used, ranging from trace samples to high-dose samples. The maximum sample volume can reach 50g or 500g.
Large-screen LCD display, real-time display of the instrument status and data, two sets of temperature measuring couples, and one set of couples real-time display furnace temperature (regardless of whether the furnace is working or not)
Another set of galvanic couples shows the sample temperature during operation.
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.
The measurement and drawing are completed automatically. The software functions can complete the routine data processing of TG, DTG, DDTG; special data processing (reaction peak area, calculation of kinetic parameters, data comparison, etc.).
The axis of abscissa can choose temperature or time as the scale.
The ordinate axis can choose absolute weight or percentage as the scale. Technical Parameters
