Measurement & Analytical Methods

Hazardous Air Pollutants (HAPs)

NCASI develops, evaluates and validates sampling and analytical methods for HAPs in air emissions, condensates and wastewater. Several of these methods are approved under the Subpart S (pulp and paper) and Subpart DDDD (PCWP) MACT rules for compliance demonstration purposes. The NCASI method to measure low levels of aldehydes and ketones in air emissions through derivatization (ISS-FP-A105.01) is one recent example.
