Patent number: 8726719Abstract: The invention provides a light weight analyzer, e.g., detector, capable of locating clandestine graves. The detector utilizes the very specific and unique chemicals identified in the database of human decompositional odor. This detector, based on specific chemical compounds found relevant to human decomposition, is the next step forward in clandestine grave detection and will take the guess-work out of current methods using canines and ground-penetrating radar, which have historically been unreliable. The detector is self contained, portable and built for field use. Both visual and auditory cues are provided to the operator.Type: GrantFiled: July 31, 2010Date of Patent: May 20, 2014Assignee: UT-Battelle, LLCInventors: Arpad A. Vass, Marcus B. Wise

Publication number: 20040015336Abstract: A system and method for detection and assessment of hazardous plumes includes at least one sensing station, the sensing station including at least one sensor for sampling a media and determining hazardous plume data. The hazardous plume data includes at least one hazardous plume component and quantitative data regarding the hazardous plume component, such concentration. A computing structure receives the hazardous plume data and determines a dispersion model including a future migration path of the plume. The dispersion model can also provide quantitative data regarding the hazardous plume component, such as the concentration associated with the projected plume as a function of time as well as the source location of the plume.Type: ApplicationFiled: July 19, 2002Publication date: January 22, 2004Inventors: James J.

Patent number: 5780717Abstract: An in-line gas monitor capable of accurate gas composition analysis in a continuous real time manner even under strong applied vacuum conditions operates by mixing an air sample with helium forming a sample gas in two complementary sample loops embedded in a manifold which includes two pairs of 3-way solenoid valves. The sample gas is then analyzed in an ion trap mass spectrometer on a continuous basis. Two valve drivers actuate the two pairs of 3-way valves in a reciprocating fashion, so that there is always flow through the in-line gas monitor via one or the other of the sample loops. The duty cycle for the two pairs of 3-way valves is varied by tuning the two valve drivers to a duty cycle typically between 0.2 to 0.7 seconds.Type: GrantFiled: April 23, 1997Date of Patent: July 14, 1998Assignee: Lockheed Martin Energy Research CorporationInventors: Marcus B. Wise, Cyril V. Thompson

Patent number: 5777214Abstract: An in-situ continuous liquid analyzing system for continuously analyzing volatile components contained in a water source comprises: a carrier gas supply, an extraction container and a mass spectrometer. The carrier gas supply continuously supplies the carrier gas to the extraction container and is mixed with a water sample that is continuously drawn into the extraction container. The carrier gas continuously extracts the volatile components out of the water sample. The water sample is returned to the water source after the volatile components are extracted from it. The extracted volatile components and the carrier gas are delivered continuously to the mass spectometer and the volatile components are continuously analyzed by the mass spectrometer.Type: GrantFiled: September 18, 1997Date of Patent: July 7, 1998Assignee: Lockheed Martin Energy Research CorporationInventors: Cyril V. Thompson, Marcus B. Wise

Patent number: 5646336Abstract: A system for continuously analyzing volatile constituents of a liquid is described. The system contains a pump for continuously pumping the liquid to be tested at a predetermined flow rate into an extracting container through a liquid directing tube having an orifice at one end and positioned to direct the liquid into the extracting container at a flow rate sufficient to atomize the liquid within the extracting container. A continuous supply of helium carrier gas at a predetermined flow rate is directed through a tube into the extracting container and co-mingled with the atomized liquid to extract the volatile constituents contained within the atomized liquid. The helium containing the extracted volatile constituents flows out of the extracting container into a mass spectrometer for an analysis of the volatile constituents of the liquid.Type: GrantFiled: May 10, 1996Date of Patent: July 8, 1997Assignee: Lockheed Martin Energy Systems, Inc.Inventors: Cyril V.

Patent number: 5272337Abstract: An apparatus for introducing gaseous samples from a wide range of environmental matrices into a mass spectrometer for analysis of the samples is described. Several sample preparing modules including a real-time air monitoring module, a soil/liquid purge module, and a thermal desorption module are individually and rapidly attachable to the sample introducing apparatus for supplying gaseous samples to the mass spectrometer. The sample-introducing apparatus uses a capillary column for conveying the gaseous samples into the mass spectrometer and is provided with an open/split interface in communication with the capillary and a sample archiving port through which at least about 90 percent of the gaseous sample in a mixture with an inert gas that was introduced into the sample introducing apparatus is separated from a minor portion of the mixture entering the capillary discharged from the sample introducing apparatus.Type: GrantFiled: April 8, 1992Date of Patent: December 21, 1993Assignee: Martin Marietta Energy Systems, Inc.Inventors: Cyril V. Thompson, Marcus B. Wise

Patent number: 4879472Abstract: Method and apparatus for detecting and differentiating organic compounds based on their electron affinity. An electron capture detector cell (ECD) is operated in a plurality of multiplexed electroncially programmable operating modes to alter the detector response during a single sampling cycle to acquire multiple simultaneous chromatograms corresponding to each of the different operating modes. The cell is held at a constant subatmospheric pressure while the electron collection bias voltage applied to the cell is modulated electronically to allow acquisition of multiple chromatograms for a single sample elution from a chromatograph representing three distinctly different response modes.Type: GrantFiled: May 19, 1988Date of Patent: November 7, 1989Assignee: The United States of America as represented by the United States Department of EnergyInventors: Marcus B. Wise, Michelle V. Buchanan

Patent number: 4721858Abstract: Method and apparatus for differentiating organic compounds based on their electron affinity. An electron capture detector cell (ECD) is operated at pressures ranging from atmospheric to less than 1 torr. Through variation of the pressure within the ECD cell, the organic compounds are induced to either capture or emit electrons. Differentiation of isomeric compounds can be obtianed when, at a given pressure, one isomer is in the emission mode and the other is in the capture mode. Output of the ECD is recorded by chromatogram. The invention also includes a method for obtaining the zero-crossing pressure of a compound, defined as the pressure at which the competing emission and capture reactions are balanced and which may be correlated to the electron affinity of a compound.Type: GrantFiled: April 21, 1986Date of Patent: January 26, 1988Assignee: The United States of America as represented by the United States Department of EnergyInventors: Michelle V.
