Abstract: An embodiment of an analysis system can include an initial multi-port valve, at least one intermediate multi -port valve, a further multi -port valve, and a time-of-flight mass spectrometer (TOF-MS). The initial multi-port valve can be configured to receive a sample. The at least one intermediate multi -port valve can be fluidly connected to the initial multi-port valve and configured to receive the sample from the initial multi-port valve. A given intermediate multi-port valve can have an ion -exchange column associated therewith. The given intermediate multi-port valve can be configured selectably to one of direct the sample through the ion-exchange column associated therewith (in a speciation mode) or bypass the ion-exchange column (in an infusion mode). The further multi-port valve can be fluidly connected with the at least one intermediate multi-port valve and configured to receive the sample from therefrom. The time-of-flight mass spectrometer (TOF-MS) can be fluidly connected to the further multi-port valve.

Abstract: A nebuliser outlet comprises an inlet end and an outlet end, a first channel and one or more second channels arranged between the inlet end and the outlet end. The first channel is configured to receive a capillary, and the one or more second channels are configured to pass gas to the outlet end. The nebuliser outlet is a single integrated component.
