The room is equipped with a FT-ICR type hybrid mass spectrometer equipped with a 7 T magnet (Bruker Apex Qe). It is coupled either to the free electron laser or to an OPO / OPA laser (2.5 -5 μm) or to a Co2 laser (10.6 μm). This arrangement makes it possible to derive the IR spectra of the ions within the mass spectrometer.

Ions are put into the gas phase thanks to an ESI or nano ESI source. The introduction line used for CID fragmentation (Collisinal Induced Dissociation), has been modified to introduce neutral molecules directly into the collision cell in order to produce an ion-molecule reaction.
This device is part of the FT-ICR national high-field mass spectrometry network
