Abstract
Resonance-enhanced multiphoton ionization (REMPI) spectroscopic techniques are under development for the continuous monitoring of toxic emissions from municipal and hazardous waste incinerators. REMPI detection schemes and detection limit data for monitoring the chloroelhylenes at part-per-billion concentrations are presented. The high sensitivity and selectivity demonstrated for the detection of tetrachloroethylene (C3C14) make it a particularly attractive surrogate for monitoring the presence of numerous other chlorinated hydrocarbon species found in incineration stack gases.
