Disclosed is a method of: providing a fiber having propylene oxide adsorbed thereon; exposing the fiber to a gaseous sample; allowing the propylene oxide to react with any chlorine in the sample to form chloro-2-propanol. The method can be used to detect potassium chlorate.

Derivitization of vaporous chlorine by propylene oxide

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.

Mixed odor delivery device (MODD)

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.
