This study demonstrates the applicability of PCB monitoring using laser ionization time of flight mass spectrometry. Picosecond 266 nm laser light ionization reduced fragmentation, with PCB detection sensitivity under ppbv (〜μg/Nm^3) that can be achieved in one minute detection time. This has great advantages in terms of real time monitoring ability compared to the conventional method, which requires several days analysis time. A prototype of the PCB monitoring device has been developed and tested in Mitsubishi Heavy Industries' PCB treatment plant. The one-minute detection time represents a substantial advance in the monitoring of exhaust gas and in compliance with safety regulations in the atmosphere surrounding work areas where PCB vessels are dismantled.
