Abstract:
Petroleum refining for processing heavier oils into gasoline and diesel fuels is a major industry in the United States but releases benzene and other toxic pollutants as part of the production process. The EPA has developed method 325 to establish protocols for refineries to measure the average benzene concentration at the perimeters of plants. 325A describes sampling methods for deployment and passive sampling onto clean thermal desorption tubes, while 325B describes laboratory analysis using thermal desorption GC-MS. This work demonstrates a full method solution with the combination of CAMSCO’s TubeTrack™ software and CDS Analytical’s 7550S thermal desorber.
