Abstract:Abstract:Improvements in electrochemical (EC) cell design, sample preconcentration, sample desorption, pyrolysis and sample transport have led to significant increases in sensitivity towards explosive detection using electrochemical NO 2 sensors. Our EC sensors have been modified to allow faster sample permeation through the sensor membrane giving sharper response peaks. Sample trapping and preconcentration has been optimized for low concentrations of explosive vapours and ICAO taggents. The trap has a low mas… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
