Abstract
This invention relates to an apparatus (10) for, and a method of, collecting and analyzing a sample of exhaust gases (16) from a mobile exhaust source. A funneling member (18) is attached to a vehicle (12) for concentrating exhaust gases (16) discharged by a moving exhaust source. The vehicle (12) is positioned behind the mobile exhaust source such that the funneling member (18) is within a stream of exhaust gases (30) being discharged by the mobile exhaust source. As the exhaust gases (16) pass through the funneling member (18), a sampling tube (22) extracts a sample of the concentrated exhaust gases (16) and routes them to an analyzing means (26) for analysis of the sample.
