title: A new external EI/CI source-ion trap system devoted to the study of ion-molecule reactions.
abstract: A new instrumental arrangement dedicated to the study of ion-molecule reactions and consists of by an electron impact/chemical ionization source mounted 420 mm away from an ion trap is described. It has been designed and developed to exclude diffusion into the ion trap of the neutral reactants from the EI/CI source and so to avoid undesired side-reactions. Its instrumental parameterization is described and some preliminary results are illustrated that show promise for the successful application of the system to the study of ion-molecule reactions.
