(AAAR) - SEMI-CONTINUOUS DETERMINATION OF WATER-SOLUBLE PARTICULATE COMPONENTS AND THEIR GASEOUS PRECURSORS: LABORATORY AND FIELD EVALUATION OF INSTRUMENTATION BASED ON WET WALL DENUDER AND ION CHROMATOGRAPHY TECHNOLOGY . Presented at International Aerosol Conference (AAAR), St. Paul, MN, September 10 - 15, 2006.
Impact/Purpose:
1. Provide the Agency with semi-continuous and real-time instrumentation for its monitoring of ozone, ozone precursors, and reaction products of ozone formation.
2. Provide the Agency with semi-continuous and real-time instrumentation for its monitoring of water-soluble PM components and water-soluble atmospheric gases.
Description:
Research conducted by EPA at its facility in Research Triangle Park, NC and by EPA, Brigham Young University (BYU), Dionex Corporation and others during field intensive studies in California, Utah and Florida has demonstrated the capability for the semi-continuous determination of water-soluble particulate components (SO42-, NO3-, NO2-, Cl-, and NH4+) and gaseous precursors (SO2, HNO3, HONO, HCl, and NH3) using instrumentation based on wet wall denuder (WWD) and ion chromatography (IC) technology.
