Patent number: 11307172Abstract: 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.Type: GrantFiled: October 25, 2018Date of Patent: April 19, 2022Assignee: Smiths Detection Montreal, Inc.Inventors: Bohdan Atamanchuk, Volodimir Bondarenko, Vlad Sergeyev, Henryk Zaleski, Daniel Levin, Mark Piniarski, Igor Kubelik, Qunzhou Bian, Simon Feldberg, Douglas J. Green, Brian Boso, Atin J. Patel

Patent number: 9778224Abstract: An ionization device includes a first electrode comprising a conductive member coated with a dielectric layer. The ionization device also includes a spine extending adjacent to and at least partially along the first electrode. The ionization device further includes a second electrode comprising conductive segments disposed adjacent the first electrode. Each one of the conductive segments contacts the spine at a respective contact location. The dielectric layer of the first electrode separates the conductive member of the first electrode from the spine and the second electrode. The ionization device is configured to create plasma generating locations corresponding to respective crossings of the first electrode and the second electrode.Type: GrantFiled: November 26, 2014Date of Patent: October 3, 2017Assignee: Smiths Detection Montreal Inc.Inventors: Igor Kubelik, Simon Feldberg, Bohdan Atamanchuk, Mark Piniarski, Mark Lekhter, Daniel Levin, Vlad Sergeyev, Henryk Zaleski

Patent number: 8901489Abstract: Looped ionization sources for ion mobility spectrometers are described. The ionization sources can be used to ionize molecules from a sample of interest in order to identify the molecules based on the ions. In an implementation, an electrical ionization source includes a wire that is looped between electrical contacts. The wire is used to form a corona responsive to application of voltage between the wire and the walls of an ionization chamber. The corona can form when a sufficient voltage is applied between the wire and the walls. A difference in electrical potential between the wire and a wall forming an ionization chamber, in which wire is contained, can be used to draw the ions away from the wire. In embodiments, the wire can be heated to reduce the voltage used to strike the corona. The ions, subsequently, may ionize the molecules from the sample of interest. The looped corona source can also be used in mass spectrometers (MS).Type: GrantFiled: June 15, 2012Date of Patent: December 2, 2014Assignee: Smiths Detection Montreal Inc.Inventors: Daniel Levin, Vlad Sergeyev, Volodimir Bondarenko, Bohdan Atamanchuk, Qunzhou Bian, Henryk Zaleski, Mark Piniarski, Simon Feldberg, Ronald Jackson
