  • Publication number: 20160138069
    Abstract: A method of determining the presence of Pseudomonas involves establishing a gaseous headspace over a surface suspected of containing at least one Pseudomonas strain and contacting at least a portion of the gaseous headspace with a capillary microextraction of volatiles (CMV) sampling device to absorb at least one component of the headspace by the CMV sampling device. The component loaded CMV sampling device is coupled to an injection port of an analytical device where the components are desorbed into the analytical device, where components are separated, detected, and identified to determine if one or more of the identified components is a biomarker for at least one Pseudomonas strain.

  • Patent number: 9267866
    Abstract: A capillary microextractor of volatiles (CMV) allows the sampling of diagnostic volatiles that can be an explosive, explosive taggant, drug, poison, decomposition products thereof, a mixture of chemicals comprising an odor signature determined from detector dog trials, or volatile organic compounds indicative of a disease or other medical condition. The CMV has a thermally stable housing with orifices to allow the contact of a gas that contains one or more diagnostic volatiles with an absorbent that extracts and concentrates the diagnostic volatiles. After sampling, the CMV with the absorbed diagnostic volatiles can be placed in an ionized gas beam and introduced into a mass spectrometer or placed in a thermal desorption unit (TDU), where, upon heating, the diagnostic volatiles are released to an inlet port of an analytical instrument.

  • Patent number: 8298666
    Abstract: An electroluminescent (EL) phosphor is described wherein each individual phosphor particle is encapsulated in an inorganic coating, preferably aluminum oxyhydroxide. The encapsulated phosphor shows an extreme insensitivity to atmospheric moisture and suffers only minor loss of initial brightness in lamps. The method of applying the coating is a hybrid process, which involves EL phosphor particles first being coated with a thin inorganic film using an atomic layer deposition (ALD) method in a fluidized bed wherein the precursors are introduced sequentially in repeated cycles, subsequently followed by an additional coating layer applied by a chemical vapor deposition (CVD) method in which the precursors are introduced simultaneously.
