Air Toxics Sampling and Analysis
(2 of 2)
EPA-approved methods for collection and analysis of
suspended particulate matter are documented in the
“Compendium of Methods for the Determination of
Inorganic Compounds in Ambient Air.”
Chapter IO-3, Chemical Species Analysis of Filter-Collected
Suspended Particulate Matter (SPM), is of considerable
importance to the air toxics ambient monitoring program.
Several different methods for speciated particulate analyses are
Each have advantages and disadvantages depending on the
target analytes and desired minimum detection limits.
For Hazardous Air Pollutant (HAP) metals, IO-3.5 (Inductively
Coupled Plasma / Mass Spectrometry (ICP/MS)) offers the
lowest detection limits.
