Patent number: 8333105Abstract: Apparatus, systems and methods are described for preconcentrators, chemical sensing systems and gas chromatographs. A preconcentrator is described that comprises a hollow enclosure containing a sorbent material. The enclosure may be a capillary tube that can be formed in to a desired shape and that may be heated. Heating may be accomplished by passing an electrical current through the capillary or other hollow enclosure form. The sorbent material can be a liquid, a solid, a porous ceramic material and/or a chemiselective polymer. The sorbent material can be coated to the inner wall of the enclosure. The hollow enclosure may be maintained in an insulated chamber. The preconcentrator acts to concentrate a vapor passed through the preconcentrator to a chemical sensing array that can detect chemicals present in the vapor. A gas passed through the hollow enclosure can provide a chemically concentrated input to a chromatographic column.Type: GrantFiled: April 30, 2010Date of Patent: December 18, 2012Assignee: Seacoast Science, Inc.Inventors: Jonathan Day Lucas, Manna Leon Warburton, Todd Mlsna, Sanjay V.

Publication number: 20070194406Abstract: A fixed parallel plate micro-mechanical systems (MEMS) based sensor is fabricated to allow a dissolved dielectric to flow through a porous top plate, coming to rest on a bottom plate. A post-deposition bake ensures further purity and uniformity of the dielectric layer. In one embodiment, the dielectric is a polymer. In one embodiment, a support layer is deposited onto the top plate for strengthening the sensor. In another embodiment, the bottom plate is dual-layered for a narrowed gap. Integrated circuit arrays of such sensors can be made, having multiple devices separated from each other by a physical barrier, such as a polycrystalline containment rim or trough, for preventing polymer material from one sensor from interfering with that of another.Type: ApplicationFiled: October 2, 2006Publication date: August 23, 2007Applicant: Xsilogy, Inc.Inventors: Sanjay Patel, Bernd Fruhberger, Erno Klaassen, Todd Mlsna, David Baselt

Publication number: 20060237310Abstract: The present invention relates to the field of chemical detection. More specifically, the invention provides devices that can detect various target analytes (e.g., chemicals and/or biological materials) present in an environment by adsorption or absorption of the target analyte(s) to or in a chemical sensing material such that an electrical parameter (e.g., capacitance, resistance, etc.) of the chemical sensing material is altered in a manner detectable by circuitry associated with the sensing electrode pair coated with the chemical sensing material. Here, the sensing electrode pair(s) of the devices of the invention are suspended over an inert substrate via one or more posts used to space the electrodes from the substrate.Type: ApplicationFiled: April 26, 2005Publication date: October 26, 2006Inventors: Sanjay Patel, Todd Mlsna, Erno Klaasen

Publication number: 20050164285Abstract: A sensor for determining the presence of an analyte is disclosed comprising a reactive layer disposed between a base plate and a movable plate. The reactive layer is configured to interact with an analyte effecting a change in capacitance between the base plate and movable plate. When the analyte has a polarity or overall Hildebrand solubility parameter that is similar to the reactive layer, the change in capacitance is caused by a swelling of the reactive layer as analyte is absorbed into the reactive layer. This results in a decrease in capacitance. When the analyte has a solubility parameter not near the reactive layer, the absorbed analyte causes the reactive layer's total polarity to increase, an effect that dominates swelling. This causes an increase in capacitance. A capacitive sensing circuit is included for measuring the change in capacitance which is indicative of the analyte exposed to the sensor.Type: ApplicationFiled: March 18, 2005Publication date: July 28, 2005Inventors: Sanjay Patel, Bernd Fruhberger, Robert Warmack, Todd Mlsna, David Baselt, Erno Klaassen

Patent number: 6435007Abstract: A sensor system that monitors agent breakthrough through a vapor barrier and related test process. The system includes a substantially airtight test chamber for retaining the vapor barrier, which may be formed of one or more layers of one or more materials. A sensor element array placed adjacent to the barrier under test includes elements that are sensitive to one or more agents of interest and elements that are insensitive to such agents. The insensitive elements provide a baseline reference signal that is compared to the output signal of the sensitive elements. As the agent contacts the array, the electrical signal output from the sensitive elements changes in comparison to that of the reference elements. The sensor array is sensitive enough to detect low levels of the agent when the agent passes through the barrier. A control system is used to regulate and monitor environmental conditions within the chamber and to process electrical signals from the sensor array.Type: GrantFiled: April 27, 2000Date of Patent: August 20, 2002Assignee: Sensor Research & Development CorporationInventors: Dean Smith, Todd Mlsna, Jeremy Hammond
