Title Selective Real-time Detection of Gaseous Nerve Agent Simulants Using Multiwavelength Photoacoustics.
Publication Date Aug 2012
Media Count 4p
Personal Author K. P. Gurton M. Felton R. Tober
Abstract An optical detection method is presented that is designed to detect and identify the presence of macromolecular gas species (e.g., organophosphate- based nerve agent simulants) at trace level concentrations. The technique is based on a modified version of conventional laser photoacoustic (PA) spectroscopy, in which optical absorption is typically measured using a single laser source. We demonstrate the ability to simultaneously measure multiple absorption-related parameters that serve as a concentration-independent identifier.
