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.

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

Patent number: 7800056Abstract: A document sampler can be arranged to receive a document in an insertion area of the document sampler. With such arrangements, a document can be directly inserted into a document sampler without an extra step of swabbing a document with a sample collection device. By eliminating the extra step of swabbing a document, the efficiency of sample detection is improved, sample detection is performed more rapidly, and operating costs of sample detection are decreased.Type: GrantFiled: October 24, 2007Date of Patent: September 21, 2010Assignee: Smiths Detection Montreal Inc.Inventors: Bill Mawer, Geoff Beyer, Mark Elliot, Mark Piniarski, Roland Link, Simon Feldberg
