ABSTRACT:
System and method for monitoring the level of a VOC or other vapor contaminant emitted in a gas stream or the like being vented at a specified pressure from an emission source. A medium of a bed of solid particles is provided within a vessel having an inlet and an outlet which is effective for separating the contaminant from the gas stream. The inlet pressure of the vessel is maintained at the specified pressure of the gas stream being vented from the emission source. The separated contaminants are concentrated in the medium which exhibits an increase in mass corresponding to the amount of the contaminant that was contained in the gas stream.
