Abstract
A device for ionizing sample particles of a sample gas flow comprises a first flow tube for providing the sample gas flow, and an introducing means for providing HSOmolecules to an interaction region. In addition the device comprises a generator for producing reagent primary ions from particles of candidate reagent gas flow essentially in a primary ion production region. The device is configured to introduce said reagent primary ions with HSOmolecules in said interaction region in order to arrange interaction between the reagent primary ions and the HSOmolecules, thereby producing HSOions and again to produce HSO4ion clusters comprising HSOions and at least two HSOmolecules via interactions of HSOwith other HSOmolecules in said interaction region. Furthermore the device is configured to introduce said HSOion clusters with the sample particles of the sample gas flow in order to provide reactions between said HSOion clusters and the sample particles, and thereby provide a sample cluster comprising the HSOion clusters and said base sample to be determined.
