$64,718Anticipated Results/Potential Commercial Applications of Research:
:An optical PL-sensing system with attendant data acquisition and electronics will be constructed. Sensitivity, stability and reproducibility will be qualified with hydrocarbon/ketone/ester mixtures or tertiary mixtures within a matrix at the 10-ppm level.The work will focus on three issues: stability of the porous silicon surface towards drift, reproducibility of the surface recognition elements from sample to sample, and sensitivity of the sensor suited for the intended application. Microfabrication issues for fieldable instrument will be planned. Small inexpensive analyzers for instantaneous monitoring could save the Food & Beverage industry more than $1 million per year per manufacturer in product recalls.
