Abstract

A mass spectrometer or ion mobility spectrometer is disclosed comprising: an ion block for receiving ions; a heater for heating the ion block; a vacuum housing; and an interface block arranged between the ion block and the vacuum housing; wherein the interface block is formed from a polymer. The polymer interface block inhibits the heat transfer from the ion block to the vacuum housing and also electrically isolates the ion block and vacuum housing. The interface block further comprises at least one conduit through the body of the interface block. This enables gas to be transmitted through the interface block to the ion block, and also enables the interface block to be cooled.
