TGA/STA-MS

Coupling by heated capillary tube
The gases evolved by the sample are collected in the TGA furnace close to the crucible. They are quickly (approx. 100 ms) transferred to the ion source of the Mass Spectrometer thanks to the pressure difference between the TGA furnace (approx. 1 bar) and MS (approx. 10-7 mbar). The gases are not exposed to a temperature lower than 300 °C during the transfer. The ionized molecules and fragments are then separated according to their m/z ratio and detected.
The intensity of one or more selected characteristic m/z can be monitored and superimposed to the mass variation signal. Full spectra can also be acquired frequently over the duration of the TGA experiment. Mass spectrometers with amu ranges up to 300 can be employed.
Supersonic System
Here the evolved gases are accelerated by a two steps pressure drop system. Their speed overcoming the speed of sound, they are instantaneously transferred to the ion source, avoiding any condensation or recombination during their route. Heavy, high boiling point molecules like metal vapors or polyaromatic compounds can thus be detected. Mass spectrometers with amu ranges up to 1024 can typically be employed.

– Features: best limit of detection, fast transfer time
– Benefits: applicable to small mass variations, easy to setup, detection of heavy molecules (with Supersonic System)
