PM 2.5 and PM 10 refers to particular matter than is smaller than 2.5 and 10 micron respectively. ALS offer testing of these parameters for stack emission sampling
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.
A variety of metals may be found in emissions. Many of these can have a negative impact on the environment and hence monitoring is needed

MORE INFORMATIONInorganic compounds like Nitrogen and sulphur dioxide are unwanted compounds in stack emission due to their potential of contributing to acid rain.
