  • INDICATING CROSS-CONTAMINATION OF VOLATILE ORGANIC COMPOUNDS BETWEEN CLOSED CONTAINERS USING A COLORIMETRIC SENSOR
    Publication number: 20220308026
    Abstract: An apparatus having: a container, a first openable vessel within the container, an analyte within the first vessel, and a vapochromic sensor within the container. The vapochromic sensor changes color on contact with a vapor of the analyte.
    Type: Application
    Filed: February 15, 2022
    Publication date: September 29, 2022
    Applicant: The Government of the United States of America, as represented by the Secretary of the Navy
    Inventors: Lauryn E. DeGreeff, Christopher J. Katilie, Janet Crespo-Cajigas
  • Mixed odor delivery device (MODD)
    Patent number: 10932446
    Abstract: An apparatus for training canines to detect complex hazardous substances from an odor mixture developed from at least two separated material components having at least two separated odors respectively. The training apparatus has a chamber base unit having at least two vial wells configured to hold separate containers of the material components and a chamber top unit having a first side facing the chamber base and a second side opposite the first side. The first side of the chamber top unit and the chamber base unit define a primary vapor mixing chamber in fluid communication with the vial wells. A mechanical seal between the chamber top and the chamber base seals the primary vapor mixing chamber. A passageway extends through the chamber top unit connecting the primary vapor mixing chamber to the second side of the chamber top unit.

  • Online chemical derivatization using a cooled programmed temperature vaporization inlet
    Patent number: 10648955
    Abstract: A method of detecting an analyte by: providing a derivatizing agent that is reactive with the analyte; delivering the derivatizing agent into a chamber; delivering a sample of a gas suspected of containing the analyte into the chamber before or after delivering the derivatizing agent, while the chamber is maintained at a temperature that retains the derivatizing agent and any analyte and that allows reaction between the derivatizing agent and any analyte in the chamber to form a derivatized analyte; warming the chamber to cause evaporation of any derivatized analyte; and delivering the derivatized analyte in the chamber into a gas chromatograph column.
