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.

Abstract: A low temperature plasma probe, a mass spectrometry system, and a method for using a low temperature plasma probe are described. In an embodiment, a low temperature plasma probe includes an intake capillary that provides an ion flow from a sample surface to a mass spectrometer; at least one low temperature plasma tube that provides low temperature plasma gas; at least one heated gas tube that provides heated gas to the sample surface, where the heated gas enhances desorption and ionization of a sample on the sample surface.

Abstract: A sample inlet device and methods for use of the sample inlet device are described that include an ion funnel having a plurality of electrodes with apertures arranged about an axis extending from an inlet of the ion funnel to an outlet of the ion funnel, the ion funnel including a plurality of spacer elements disposed coaxially with the plurality of electrodes, each of the plurality of spacer elements being positioned between one or two adjacent electrodes, each of the plurality of spacer elements having an aperture with a diameter that is greater than a diameter of each adjacent electrode. The ion funnel is configured to pass an ion sample through the apertures of the electrodes and the spacer elements to additional portions of a detection system, such as to a mass analyzer system and detector.

Abstract: An intermittent sample inlet device and methods for use of the intermittent sample inlet device are described that include an orifice plate with an entrance orifice and a rotating skimmer with a skimmer orifice, where the rotating skimmer is disposed between the orifice plate and a vacuum chamber wall. The rotating skimmer rotates so that the skimmer orifice intermittently aligns with the entrance orifice and allows an ion sample to pass through to a mass analyzer.
