Estimating the term…
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.
Sampler for collecting at least one analyte from a sample, whereby the sampler is configured as a sampling unit, which is capable of sequentially collecting analytes from individual samples from a plurality of solid samples, whereby the sampling unit comprises a sample holder with several chambers wherein each chamber is configured for receiving an individual sample whereby each of the chambers comprises an inlet and an outlet, such that a gaseous fluid flow can pass through each of the chambers, whereas the inlets and the outlets are arranged on opposite sides of the chamber and whereby the sample holder comprises an inlet closing member which is configured to close and open at least a part of the inlets of the chambers as well as an outlet closing member which is configured to close and open at least a part of the outlets of the chambers whereby the inlet closing member and/or the outlet closing member are moveable with respect to the sample holder or vice versa, especially such that, upon a relative movement between the sample holder and the inlet closing member and/or the outlet closing member, at least a part of the inlets of the chambers and/or at least a part of the outlets of the chambers can be opened or closed simultaneously.
