title: Performance and application potential of ion-molecule reaction mass spectrometry (IMR-MS) in the analysis of complex gas mixtures.
abstract: The mild ionisation technique of IMR mass spectrometry in combination with a tuneable cell for the charge transfer reaction allows to study mixtures of small molecules with low fragmentation and chemical selectivity. Temporal resolution down to 100 ms and quasisimultaneous multicomponent trend analyses can be combined in a flexible way responding to changing analytical requirements. The research instrument of ATOMIKA provides digital control over a range of parameters and ionisation sources. Its performance is characterised in several applications ranging from purity tests over the detection of small oxygenate organic molecules to more complex reaction systems of heterogeneous catalytic performance testing.
