ION MOLECULE REACTOR AND SETUP FOR ANALYZING COMPLEX MIXTURES

An ion molecule reactor for generating analyte ions from analytes comprises: a) a reaction volume in which reagent ions can interact with the analytes in order to form analyte ions; b) at least one analyte inlet for introducing the analytes along an inlet path into the reaction volume whereby， preferably， the inlet path runs essentially along at least a first section of the predefined transit path in the reaction volume; c) at least one reagent ion source and/or at least one reagent ion inlet for providing reagent ions into the reaction volume; d) optionally， at least one ion guide comprising an electrode arrangement which is configured for producing an alternating electrical， magnetic and/or electromagnetic field， that allows for guiding the reagent ions and/or the analyte ions at least along a section of the predefined transit path， preferably along the whole transit path， through the reaction volume. There is also provided a sampler comprising one or more chambers， wherein each chamber is configured for receiving an individual sample and comprises an inlet and an outlet， such that a gaseous fluid flow can pass through each of the chambers.
