A mass spectrometer is disclosed comprising a rotatable isolation valvehaving a curved, spherical, cylindrical or concave portion. At least a portion of an ion guideis positioned so as to extend within a swept volume of the isolation valveenabling the ion guideto be positioned close to a second downstream ion guideand for ions to be transmitted from the firstion guide to the second ion guidewith high ion transmission efficiency.

Device for rapid exchange of ion sources and ion transmission devices

A nozzle for an ionisation source comprises: a light passage having an inlet end and an outlet end; and a gas flow passage in fluid communication with the light passage, wherein the gas flow passage is configured to convey, in use, a flow of gas into the light passage such that the flow of gas travels substantially towards the outlet end of the light passage.
