SIMULTANEOUS THERMAL ANALYSIS AND MASS SPECTROMETRY
Measures the gases that are released as a result of weight changes and endothermic or exothermic reactions.
Thermo Mass Photo is a simultaneous instrument that uses a skimmer-type interface to combine STA with mass spectrometry (MS).
It has two separate modes for qualitative analysis of evolved gases, namely electron ionisation (EI) and soft ionisation by photoionization (PI), both of which are available with only one click on the software.
Interface similar to a skimmer
We were able to accomplish a more compact design than the traditional capillary approach because it uses a skimmer type interface, which is made up of a twin orifice structure based on the jet separator principle.
PI stands for Photo Ionization.
The gentle ionisation method, which uses a VUV (vacuum ultraviolet) light, allows molecule ions to be ionised without fragmentation. We can confirm the molecular ions (parent ions) in a fragment-free spectrum using this method.
Since the traditional electron ionisation system is in place, we may obtain a more thorough evolved gas analysis result by comparing the EI and PI results.
