Abstract
A mass spectrometer is disclosed comprising an atmospheric pressure interface comprising an ion block or sub-assembly having an internal passage. The atmospheric pressure interface further comprises either an inner sampling cone, a capillary interface or other gas limiting interface. The mass spectrometer comprises a clamp formed from a thermally insulating material and a removable outer gas cone which is slidably inserted into or onto the clamp so that the outer gas cone is retained by the clamp in use. The clamp is arranged and adapted to be pushed by a user into engagement with the ion block or sub-assembly so as to position the outer gas cone adjacent the inner sampling cone, capillary interface or other gas limiting interface so as to secure the outer gas cone to the ion block or sub-assembly and to form a gas tight seal with the ion block or sub-assembly without use of mechanical fasteners.
