Abstract: An autosampler for obtaining mass spectra from a plurality of fluid samples, in particular gaseous samples including a plurality of containers including sample sources providing the samples, wherein each one of the containers provides a docking port for being connected with a connector for enabling access to an inside of the respective container via the connector in order to obtain the respective sample from the respective container via said connector. The autosampler further includes an ionisation source for ionising at least a part of the samples, and a mass analyser for obtaining the mass spectra from the ions. The ionisation source is moveable within the autosampler sequentially to each of the containers for connecting the connector to the docking port of the respective container for collecting the sample from the respective container for ionising at least a part of the sample and obtaining the mass spectra from the ions.

Abstract: 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.
