The development of a carbonyl sampler for ENOM/PAM sites
- XonTech, Inc., Van Nuys, CA (United States). Environmental Systems Group
In accordance with the Clean Air Act Amendments of 1990, rules were developed for the establishment of the Enhanced Ozone Monitoring Network and Photochemical Assessment Monitoring Stations (PAMS) in ozone nonattainment areas. These rules require the stations to collect ambient air measurements for a target list of meteorological measurements of surface and upper air. Included in the VOCs are several aldehydes. In the past, canister sampling and analysis for C{sub 2}-C{sub 10} hydrocarbons have been the subject of much discussion and implementation. Presently carbonyl compounds, especially low molecular weight aldehyde and ketones are receiving increased attention as toxic air pollutants or as intermediates in many photochemical reactions. Because these compounds occur in trace concentrations ranging from sub-parts per billion to higher parts per billion in the atmosphere, sampling for carbonyl compounds poses some challenging problems. XonTech, Inc. has designed a carbonyl sampler suitable for Ozone Precursors Monitoring Program or the PAMS requirement of short time monitoring around the clock. The design, features, and operation of this sampler will be presented.
