Abstract: An ion transfer tube assembly, a mass spectrometry system, and a method for providing an ion stream to an ion detection device are described that include using an ion transfer tube that provides a coaxial sheath gas flow. In an implementation, an ion transfer tube assembly includes an ion transfer tube for delivering the ion stream, where a sheath gas flows through the ion transfer tube, and where the ion transfer tube receives the ion stream from a first conduit coupled to an ion source; a pump fluidly coupled to the ion transfer tube, where the pump causes the sheath gas to flow through the ion transfer tube, where the ion stream is separated from the ion transfer tube walls by the coaxial sheath gas flow, and where the ion stream is received by a second conduit coupled to the ion detection device.
