Method 202

This isokinetic method is used to measure Condensable Particulate Matter (CPM) from stationary source emissions after particulate matter has been removed by a heated filter, such as in Method 5, 17 or 201A.  The CPM is collected in dry impingers.  The impinger contents are purged with nitrogen (N2) immediately after sample collection to remove dissolved sulfur dioxide (SO2) gases from the impinger.  The organic and aqueous fractions are dried and the residues are weighed. The total of the aqueous and organic fractions represents the CPM.
