REAL-TIME NAPHTHALENE MONITORING USING AN ULTRA FAST GAS CHROMATOGRAPH
Abstract:Odors from the remediation of former Manufactured Gas Plant (MGP) sites can slow down or stop remedial activities. Coal tar is usually found at these sites and naphthalene is a significant odor causing component from coal tar. The zNose® Model 4200 Ultra- Fast Gas Chromatograph was used to monitor odor as a function of naphthalene concentration at an MGP remediation. Ambient air concentrations measured from the zNose® confirmed measurements obtained by personnel trained in the ASTM E544-99 odor intensity scale. The naphthalene concentration data provided the client with a database of quantifiable odor measurements that could be used as a liability defense in case of litigation.
