  • Patent number: 11307172
    Abstract: An ion detection assembly is described that includes a drift chamber, an inlet assembly, and a collector assembly. The drift chamber is formed of substantially non-conductive material and/or semi-conductive material. A patterned resistive trace is deposited on one or more of an interior surface or an exterior surface of the drift chamber. The patterned resistive trace is configured to connect to a source of electrical energy. The inlet assembly and the collector assembly are in fluid communication with the drift chamber. The inlet assembly includes an inlet for receiving a sample, a reaction region for ionizing the sample, and a gate for controlling entrance of the ionized sample to the drift chamber. The collector assembly includes a collector plate for collecting the ionized sample after the ionized sample passes through the drift chamber.

  • Publication number: 20190131118
    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.
