Abstract
A probe assembly is disclosed comprising an inlet for receiving an eluent from a chromatography device; an outlet for delivering the eluent to an ion source of a mass spectrometer; and an attachment device for attaching the outlet to the mass spectrometer. The outlet comprises an electrically conductive capillary and an electrically conductive member surrounding at least part of the electrically conductive capillary. The electrically conductive member is arranged to receive a voltage upon connection of the attachment device to the mass spectrometer and the electrically conductive member is arranged to provide an electrical connection from the electrically conductive member to the electrically conductive capillary.
