STA Synchronous thermal analyzer STA combines TGA (Thermogravimetric Analysis) with DTA (Differential Thermal Analysis) or DSC (Differential Scanning Calorimetry), in which we can get the information of TG and DTA or DSC in synchrony using the same sample during the same operation.
APPLICATION
Widely used in research and development, process optimization and quality monitoring in various fields such as plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials and composite materials
Measure and research characteris
- DSC: Melting and crystallization, phase change, reaction temperature and heat, heat of combustion and specific heat capacity, etc
- TG: Thermal stability, decomposition, REDOX, adsorption and adsorption, free water and gesso content, ingredients proportion computation, etc
Structural advantages
- Furnace body is heated by double-row winding of precious metal nickel-chromium(STA2000(STA200)) & Platinum rhodium(STA3000(STA300)) alloy wire, which reduces interference and is more resistant to high temperatures.
- Tray sensor is made of precious metal nickel-chromium(STA2000) & Platinum rhodium(STA3000(STA300)) alloy, which has advantages of high temperature resistance, oxidation resistance, and corrosion resistance.
- The power supply, circulating heat dissipation part is separated from the host, reducing the influence of heat and vibration on the micro-thermal balance.
- It adopts an open-top structure, which is convenient to operate. It is difficult to move furnace body up to place sample, and it is easy to cause damage to sample rod.
- The host adopts heat insulation device to isolate the heat influence of the heating furnace body on the chassis and the micro-thermal balance.
- The furnace body can be replaced according to customer requirements
Controller and software advantages
- Using imported 32bit ARM processor Cortex-M3 core, sampling speed, processing speed is faster.
- 24bit four-channel sampling AD collects DSC signal, TG signal and temperature T signal.
- Power supply and water circulation part are individually controlled by 8bit single-chip microcomputer to separate the host and the cooling part without interfering with each other, but the two are closely connected, and the cooling part is controlled by the host.
- USB two-way communication is adopted between the software and the instrument to fully realize remote operation. The parameter setting of the instrument and the operation and stop of the instrument can be carried out through the computer software.
- 7 inch full color 24bit touch screen, better man-machine interface. TG calibration can be achieved on the touch screen
