An integral part of efforts to regulate and control air pollution emissions is collection and analysis of exhaust stream samples to determine the concentration and flow rate of pollutants released to the atmosphere. The U.S. Environmental Protection Agency (EPA) and its counterparts in other countries have developed formal methods defining the hardware and procedures for collecting and analyzing samples to quantify emissions of individual pollutants. A significant number of these methods involve manual extraction of a sample from a facility’s exhaust stack, sample recovery and subsequent laboratory analysis to quantify concentration of a specific pollutant(s) in the sample.
