Real time analyzer of volatile organic compounds (VOCs). BTrap solution associates Chemical Ionization like Proton Transfer Reaction, with a new compact and low cost Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometer. BTrap is rugged and can be installed on site.
BTrap features:
- Monitoring: measurements every second.
- Screening: broadband detection.
- Accurate measurement: high mass resolution.
- Direct quantification.
- Transportable device.
Ionization
Soft Ionization: use of Chemical Ionization (CI) methods such as PTR (Proton Transfer Reaction) ionization. Chemical Ionization provides less fragmentation than Electron Impact, which allows a better identification of the compounds.
The most commun reactions used for VOCs detection are Proton Transfer Reaction from H3O+, charge transfer reaction from O2+ , NO+.
Negative ions, for example O–, can also be used.
