Abstract
Ionisation of small molecules via ion-molecule reactions (IMR) offers the possibility to reduce fragmentation caused by high energy electron impact ionisation. Widely varying rate constants for the IMR processe s allow to introduce additional species selectivity together with the mass selection in a quadrupole system. A comparison between low energy electron impact ionisation and IMR illustrates the potential of this new ionisation method in gas analysis applications.
