The fiber optic ring is coupled to a sensor which has a portion thereof, between the input and output, exposed to the sample gas or sample liquid. The sensor has an enhanced evanescent region. A processor is coupled to the receiver and determines the level of trace species in the gas or liquid sample based on the rate of decay of the radiation within the fiber optic ring.Type: GrantFiled: March 27, 2006Date of Patent: March 17, 2009Assignee: Trustees of Princeton UniversityInventors: Kevin K.

Patent number: 7454945Abstract: A calibration assembly generates elemental mercury and oxidized mercury for calibrating components of a mercury monitoring system, including making necessary adjustments to efficiencies of a mercury compound converter and an elemental mercury detector. The calibrator generates an elemental mercury sample having a known elemental mercury concentration, [Hg0]1 and combines an oxidizing component with the elemental mercury sample, thereby producing a reduced concentration of elemental mercury [Hg0]2 within the sample. The calibrator measures the concentration of elemental mercury [Hg0]2 within the sample and calculates a difference between the known elemental mercury concentration, [Hg0]1 and the reduced concentration [Hg0]2. The difference between [Hg0]1 and [Hg0]2 is substantially equal to the concentration of oxidized mercury produced by the calibrator.Type: GrantFiled: September 27, 2006Date of Patent: November 25, 2008Assignee: Thermo Electron, Inc.Inventors: Dieter Kita, James H. Grassi, Jeffrey Socha, Bryan A. Marcotte

Patent number: 7442555Abstract: A mixed potential sensor device and methods for measuring total ammonia (NH3) concentration in a gas is provided. The gas is first partitioned into two streams directed into two sensing chambers. Each gas stream is conditioned by a specific catalyst system. In one chamber, in some instances at a temperature of at least about 600° C., the gas is treated such that almost all of the ammonia is converted to NOx, and a steady state equilibrium concentration of NO to NO2 is established. In the second chamber, the gas is treated with a catalyst at a lower temperature, preferably less than 450° C. such that most of the ammonia is converted to nitrogen (N2) and steam (H2O). Each gas is passed over a sensing electrode in a mixed potential sensor system that is sensitive to NOx. The difference in the readings of the two gas sensors can provide a measurement of total NH3 concentration in the exhaust gas. The catalyst system also functions to oxidize any unburned hydrocarbons such as CH4, CO, etc.Type: GrantFiled: December 22, 2005Date of Patent: October 28, 2008Inventors: Balakrishnan G. Nair, Jesse Nachlas

Patent number: 7323343Abstract: An analytical system is provided for determining nitrogen monoxide, nitrogen dioxide and ozone concentrations in air samples. An ultraviolet light source 4 is used to alter the equilibrium between nitrogen dioxide and oxygen on the one hand and nitrogen monoxide and ozone on the other. Dynamic measurement of ozone concentration with time while ultraviolet irradiation is pulsed enables each gas concentration to be calculated without requiring input gases to be scrubbed. An aApparatus 101 is further provided to provide a controlled flow of gas to a sensor 103 attached to a high altitude balloon while sheltering it from the elements and allowing for affects of temperature, said apparatus comprising a shield 104 and a gas conducting means which uses the venturi effect to control air flow or has a hole to allow water to drain without affecting air flow past the sensor.Type: GrantFiled: July 13, 2004Date of Patent: January 29, 2008Assignee: Cambridge University Technical Services LimitedInventors: Richard Anthony Cox, Roderic Lewis Jones

Patent number: 7297549Abstract: A method of determining bias in a measurement of a constituent concentration level in a sample gas is provided. The method comprises establishing a sample gas flow from an emission stream into a sample gas line of an emissions monitoring system. The method further comprises removing water from the sample gas flow and cooling the sample gas flow to a temperature below about 41° F. to produce a cooled, dried sample gas flow. The constituent concentration level is then determined for the cooled, dried sample gas flow. The method further comprises introducing a span gas having a known span gas constituent concentration level into the sample gas flow to form a combined sample and span gas flow, the span gas being introduced at a desired span gas flow rate. The method still further comprises removing water from the combined sample and span gas and cooling the combined sample and span gas to a temperature below about 41° F. to produce a cooled, dried, combined sample and span gas flow.Type: GrantFiled: March 6, 2002Date of Patent: November 20, 2007Assignee: General Electric CompanyInventors: William Steven Lanier, Glenn England

Patent number: 7294249Abstract: Microtechnologically prepared component as a flow cytometer. The component contains a preparation area to specifically influence and separate the particles, preferably by dielectrophoresis, a measuring channel area for characterizing the particles, and a sorting area for sorting the particles identified in the measuring channel area by dielectrophoresis. The sorting includes switching elements which permit active guidance of the particles into two or more subchannels corresponding to the criteria which have been registered in the measuring channel area. With a component configured in this way for the use of a flow cytometer, quick and precise sorting of particles, in particular biological cells in a suspension, can be implemented.Type: GrantFiled: January 31, 2003Date of Patent: November 13, 2007Assignee: Leister Process TechnologiesInventors: Shady Gawad, Martin Wüthrich, Philippe Renaud

Patent number: 7229594Abstract: The invention provides a device for dispensing accurately-controlled small quantities of at least one liquid, comprising a liquid supply (L); a gas supply (G), arranged to selectively supply a gas pressure; and a capillary duct (20) adapted to be filled with liquid to be dispensed, and to eject the liquid. The device has a filling configuration wherein liquid from the supply is in contact with an end (20a) of the capillary duct to fill the capillary duct with liquid; and a liquid separation and ejection configuration, in which liquid remaining in the liquid supply is separated from liquid that fills the capillary duct to form a discrete quantity (V) of liquid filling the capillary duct (20) out of contact with the remaining liquid of the liquid supply. The capillary duct, filled with this discrete quantity (V) of liquid then has one end in contact with the gas supply and another end in contact with the atmosphere.Type: GrantFiled: April 3, 2001Date of Patent: June 12, 2007Assignee: Parabol Technologies S.A.Inventors: Philippe Renaud, Alain Donzel

Patent number: 7189363Abstract: Of a gas detector 100, a chamber 105 formed between a center cover 150 and a cover 160 is a part of an air flow channel AF. A first shielding plate 165 is provided in the chamber 105. Water droplets that have entered the chamber from a chamber entrance 103 with air hit and adhere to an entrance-opposed surface 165E of the first shielding plate 165. The water thus adhering to the surface is pushed by the air flowing along the entrance-opposed surface 165E and by gravity, to thereby advance downward. The water then drips downward and is accumulated on a bottom wall surface 105WD which serves as an upper surface of a bottom wall section 161WD. The water is pushed by the flow of air, to thereby advance toward a chamber exit 104. The water is then drained downward from the chamber exit 104.Type: GrantFiled: May 23, 2003Date of Patent: March 13, 2007Assignee: NGK Spark Plug Co., Ltd.Inventors: Norimasa Osawa, Kazuto Hirai, Yuichi Koyama
