Q50 Thermogravimetric Analysis (TGA)

Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. The Q50 features a vertical beam balance design (sample capacity: 1000 mg) that supports precise TGA (balance sensitivity: 0.1 µg) measurements. A purge gas system with digital mass flow control and integral gas switching capability provides for precise metering of purge gas to the sample and reference pans. A separate gas inlet tube delivers reactive or inert gas to the sample. The Q50 also includes Advantage software for complete automatic experimental control and Universal Analysis software for comprehensive data analysis. The system can go from room temperature to 1000 oC, and can set to equilibrate at lower temperatures. Pans are provided by the user, most often alumina and platinum. If using aluminum pans the maximum temperature is 600 oC.
