Improved methods for onsite measurement of multiple volatile organic compounds are needed for process control, monitoring, and remediation. This Phase I SBIR project sets forth an optical measurement method that meets these needs. The proposed approach provides an instantaneous measure of individual compounds with extremely low cross- sensitivity and minimal matrix effects. This high degree of selectivity is especially important in monitoring industrial processes that involve hazardous air pollutants such as benzene. The approach combines a rugged light source and inexpensive, high- performance digital electronics to achieve a compact, cost-effective instrument. Fiber optic compatibility results in flexible instrument location and permits multiplexing among several nearby measurement sites.
