Analytical method & sampling procedure

Particulate Target Analyte	Applicable Method
Total Suspendable Particulate (TSP)	M5, M5D, M17, M201A
Particuclate Matter <10microns (PM <10)	M201A
Particulate Matter <2.5microns (PM <2.5)	M201A
Inorganic Condensible Particulate	M202, RM55
Organic Condensible Particulate	M202, RM55

All of these non-condensable particulate targets are determined gravimetrically, either from filter capture or acetone rinse residues. The capture of PM<2.5 and/or PM<10 is facilitated with the use of appropriately sized in-stack cyclones.

Condensable particulate are captured in impinger contents and determined by liquid/liquid extraction of the aqueous impinger content. Both the organic and aqueous phases of the extraction are determined as gravimetric residues. The aqueous residue is the inorganic condensable particulate and the organic residue is the organic condensable particulate.
