"In Phase I of this project, an innovative non-specific colorimetric chemisty was developed and fabricated for detecting hydrogen cyanide, cyanogen chloride, hydrogen fluoride, phosgene and s-mustard and nerve agent simulants, simultaneously. Two of thefabricated colorimetric indicators fulfilled the desired requirements in terms of sensitivity and non-specificity of the targeted warfare agents and simulants. A novel, non-specific, colorimetric chemistry proved feasible for the detection of majorclasses of organic vapors.In this project, the colorimetric, non-specific chemistry developed in Phase I will be optimized and used for ESLI application. The sensitivity and stability of the ESLI will be assessed and optimized accordingly. The overall performance of the ESLI willbe optimized by conducting ex-situ testing. In addition, shelf-life tests will be conducted followed by optimization of the ESLI performance, if needed. The design and optimum location of the ESLI in the mask filter will be determined. Afterimplementing the ESLI in the modified mask, in-situ assessment will be conducted to optimize the performance of the ESLI."
