Abstract: The invention relates to an autosampler (1) for obtaining mass spectra from a plurality of fluid samples, in particular gaseous samples. This autosampler (1) comprises a plurality of containers (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) comprising sample sources (3.1, 3.2, 3.3, 3.4, 3.5, 3.6) providing the samples, wherein each one of the containers (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) provides a docking port (4.1, 4.2, 4.3, 4.4, 4.5, 4.6) for being connected with a connector (5) for enabling access to an inside of the respective container (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) via the connector (5) when the connector (5) is connected to the respective docking port (4.1, 4.2, 4.3, 4.4, 4.5, 4.6) in order to obtain the respective sample from the respective container (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) via said connector (5). Thereby, the connector (5) is connectable to and detachable from each docking port (4.1, 4.2, 4.3, 4.4, 4.5, 4.6). The autosampler (1) further comprise an ionisation source (6) for ionising at least a part of the samples to ions, wherein the ionisation source (6) is fluidly coupled to the connector (5) for receiving the samples from the containers (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) via the connector (5). Furthermore, the autosampler (1) comprises a mass analyser (7) for obtaining the mass spectra from the ions, the mass analyser (7) being fluidly coupled to the ionisation source (6) for receiving the ions from the ionisation source (6) for obtaining the mass spectra from the ions. The ionisation source (6) is moveable with the connector (5) within the autosampler (1) sequentially to each one of the plurality of said containers (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) for connecting the connector (5) to the docking port (4.1, 4.2, 4.3, 4.4, 4.5, 4.6) of the respective container (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) for collecting the sample from the respective container (2.1, 2.2, 2.3, 2.4, 2.5, 2.6) for ionising at least a part of the sample to ions and obtaining the mass spectra from the ions. Furthermore, the invention relates to a method for operating the autosampler (1).
