Thermal Gravimetric Analysis using Mass Spectrometry. - Monitoring and Testing

The Aspec Mass Spectrometer system is ideal for interfacing with most Thermal Gravimetric Analysers. By connecting the specially designed, heated Mass Spectrometer sample Inlet probe, evolved gases from a heated sample within the TGA reactor can be measured and recorded with respect to time. In addition, both the temperature ramp (profile) and weight loss signals from the TGA can be integrated directly into the Mass Spectrometer software. It is also important to start the data acquisition of both instruments (TGA and MS) at the same time. There is a built in digital “trigger input signal” that allows this. In this way Time t=0 can be synchronised to both instruments.
