thermo gravimetric analyzer

 

Product introduction:

Thermogravimetric analysis (TG, TGA) is to observe the change of sample quality with temperature or time in the process of heating, constant temperature or cooling, the purpose is to study the thermal stability and composition of materials. It is widely used in the research and development, process optimization and quality control of plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials and composite materials.

The following characteristics of measurement and research materials:

Thermal stability, decomposition process, adsorption and desorption, oxidation and reduction, quantitative analysis of components, influence of additives and fillers.

Structural advantages:

1. The furnace body is heated by double-row winding of precious metal nickel-chromium alloy wire, which reduces interference and is more resistant to high temperatures.

2. The tray sensor is made of precious metal nickel-chromium alloy and has the advantages of high temperature resistance, oxidation resistance and corrosion resistance.

3. The power supply, circulating heat dissipation part is separated from the host, reducing the influence of heat and vibration on the micro-thermal balance.

4. It adopts an open-top structure, which is easy to operate. It is difficult to move the furnace body up to place the sample, and it is easy to damage the sample rod.

5. The host uses a water area constant temperature device to isolate the thermal influence of the heating furnace body on the chassis and the micro-thermal balance.

6. The furnace body can be replaced according to customer requirements

Controller and software advantages:

1. Using imported 32bit ARM processor Cortex-M3 core, sampling speed and processing speed are faster.

2.24bit four-channel sampling AD collects DSC signal, TG signal and temperature T signal.

3. The 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.

4. The USB two-way communication is adopted between the software and the instrument, which fully realizes remote operation. The parameter setting of the instrument and the operation stop of the instrument can be carried out through the computer software.
