Paper based sensors for detection of low concentrations of methyl iodide and methyl bromide, dibromo ethylene and other alkylating agents in air.
Researchers at the University of California, Davis have developed paper-based colorimetric sensors that can rapidly detect very low concentrations of methyl iodide and methyl bromide in air. The detection limit for methyl iodide and methyl bromide is 200 and 800 ppb, respectively. These sensors can be employed in agricultural fields and other aerosol applications to detect human exposure levels of either chemical.
