Method for rapid on-site identification of VOCs
Keywords: field analysis,gas chromatograph,mass spectrometer,toxic industrial chemicals,thermal desorption Abstract: Rapid on-site identification of volatile organic compounds (VOCs) in ambient air is an important first step in remediation efforts. This study describes modification of a commercially available, portable GC/MS system and development of an analysis protocol for rapid (<3 min) sampling and identification of VOCs typically found at contaminated sites at the low ppbv level.
