TG-DSC(STA) Synchronous Thermal Analyser
TGA is the observation of changes in the mass of a sample with temperature or time during warming, constant temperature or cooling, with the aim of studying the thermal stability and components of a material.
Testing and researching the properties of materials
Thermal stability, decomposition processes, adsorption and desorption, oxidation and reduction, quantitative analysis of constituents, effects of additives and fillers, water and volatiles, reaction kinetics.
Product Advantage:
The heating of the furnace body adopts double-row winding of precious metal nickel-chromium alloy wire, which reduces interference and is more resistant to high temperature.
Upward opening lid structure, easy to operate. It is difficult to move up the furnace body to put the sample operation, easy to cause damage to the sample rod. Adopt USB two-way communication between software and instrument, fully realise remote operation.
7 inch full colour 24bit touch screen, better man-machine interface.

- Furnace body heating adopts customized nickel chrome wire double row winding system, reduce interference, more high temperature resistance.
2. Tray sensor, made of alloy wire seiko, with high temperature resistance, oxidation resistance, corrosion resistance and other advantages.
3. Power supply, the circulation cooling part is separated from the main engine to reduce the influence of heat and vibration on the microthermal balance.
4. The upper open cover structure is convenient to operate. It is very difficult to put samples in the upper moving furnace body, and it is easy to damage the sample bar.
5. The machine adopts isolated heating furnace body to the thermal impact of the chassis and micro thermal balance.
6. Furnace body can be replaced according to customer requirements.
How can the TGA be used to compare two similar products?
Here two (2) types of coffees are compared, Zimbabwe in blue and Columbian in
red, using the same method conditions. The solid lines are the weight loss curves
and the dashed lines are their respective derivatives. The differences are easily
displayed, but it will take a coffee scientist to interpret the significance of the difference.
How can the TGA be used as a QA/QC tool to ensure products meet their material specifications?
here is a fiberglass reinforced printed circuit board. This analysis determines the amount of resin and the amount of fiberglass used in this material. The delta Y calculation was used to determine the component percentages. Resin = 44.144%; Glass = 56.854%. The resin decomposes in two steps, first rapidly, then slows as the last remaining resin decomposes.
Can the TGA be used to identify safe operating temperatures in various gases?
Here is an example of a weight gain experiment. A manganese sample was
run in a nitrogen atmosphere. The sample purge rate was 30 mL/minute. The delta Y calculation with calculation limits were arbitrarily set at 115 °C and 1190 °C. In this experiment the weight gain is due to the formation of manganese nitride. When manganese is run in argon, there is no weight change.
