Chemical Speciation -
Laboratory Standard Operating Procedures (SOPs)

Chemical Speciation Navigation

The Chemical Speciation Network (CSN) routinely measures PM2.5 mass, elements, ions, and carbon species. Several SOPs are used to support the laboratory operations for the analysis of these species and the list of routine SOPs are provided below.

In addition, there are SOPs that are used to support laboratory operations for optional or supplemental analyses and they are listed at the bottom of this page. The optional SOPs are available for use in special projects as needed and not used in the routine CSN.
