Patent number: 8319177Abstract: An ion mobility spectrometer is described having an ion filter in the form of at least one ion channel having a plurality of electrodes. A time-varying electric potential applied to the conductive layers allows the filler to selectively admit ion species. The electric potential has a drive and a transverse component, and in preferred embodiments each of the electrodes is involved in generating a component of both the drive and transverse fields. The device may be used without a drift gas flow. Microfabrication techniques are described for producing microscale spectrometers, as are various uses of the spectrometer.Type: GrantFiled: May 6, 2010Date of Patent: November 27, 2012Assignee: Owlstone Ltd.Inventors: Paul Boyle, Andrew H.

Patent number: 7507972Abstract: A compact ionization source includes first and second electrodes, each having a plurality of fingers that are interdigitated with each other. The spacing between the first and second electrode, preferably less than 1 mm, creates a large electric field when a potential is applied across the first and second electrodes. The large electric field creates an ionization volume between the fingers of the first and second electrode and ionizes a portion of the molecules occupying the ionization volume. The interdigitated fingers of the first and second electrodes allow for a narrow gap separating the electrodes while presenting a large flow area for ionizing molecules for downstream analysis.Type: GrantFiled: October 10, 2005Date of Patent: March 24, 2009Assignee: Owlstone Nanotech, Inc.Inventors: Martyn Rush, Paul Boyle, David Ruiz-Alonso, Andrew Koehl, Russell Parris, Ashley Wilks

Publication number: 20080017790Abstract: There is no mask on the market or registered with the USPTO that uses ultraviolet light to kill air-borne viral and bacterial contaminants. The invention will ensure that if an individual must perforce be exposed to contaminated air as a result of natural or manmade events, then that individual will be able to use the Ultraviolet Light Assisted Protective Breathing Mask (the “ULAP Breathing Mask”) to kill whatever known or unknown viruses or bacteria may be in the vicinity. The ULAP Breathing Mask kills these contaminants before inhaled air ever reaches the filters. The prototype weighs approximately three pounds, and so is easily portable and is practical.Type: ApplicationFiled: July 20, 2006Publication date: January 24, 2008Applicant: Owlstone Nanotech Inc.Inventors: Paul Boyle, Martyn Rush, David Ruiz-Alonso, Andrew H.

Patent number: 7306649Abstract: The present invention relates to a three dimensional preconcentrator and inlet heater. The preconcentrator consists of a substrate with passageways, a conductive material coated to the top and the bottom of the substrate and an adsorbent coating covering the entire substrate. This substrate is suspended in a holding frame by a connecting bridge. The preconcentrator may also include a resistor and a proportional-integral-differential controller. The device may be used inline with a detector and can be retrofitted to existing devices. An array of preconcentrators may also be formed. The invention also relates to methods of use of the preconcentrator and methods of manufacture. A method of use includes contacting an analyte and a preconcentrator, allowing the analyte to adsorb to the preconcentrator and then desorbing the analyte. A method of manufacture involves applying the adsorbent coating by misted chemical deposition.Type: GrantFiled: September 30, 2005Date of Patent: December 11, 2007Assignee: Advance Nanotech, Inc.Inventors: Paul Boyle, David Ruiz-Alonso, Andrew Koehl, Martyn Rush, Russell Parris, Ashley Wilks
