Evaluation of an intelligent multi-canister/multi-cartridge sampler for the collection of ozone precursors
- Wisconsin Dept. of Natural Resources, Madison, WI (United States)
Air monitoring requirements for Enhanced Ozone Monitoring (EOM) set down in the 40 CFR Part 58 require the collection of 8 three hour Volatile Organic Compound (VOC)/carbonyl samples each sampling day. To meet EOM monitoring requirements for Southeastern Wisconsin, the authors have designed and built a sampler capable of collecting multiple canisters (for VOCs) and multiple cartridges (for carbonyls). The sampler is comprised of three modular units, the canister collection system, the cartridge collection system, and a personal computer which acts as an intelligent controller. The intelligent controller will track all samples from the sampler setup, through sampling, to sampler take down. Relevant sampling data such as initial canister vacuum, final canister pressure, and sampling flow rates are all recorded by the sampler. At the completion of the sampling episode, all sampling data are down loaded to the project database. The authors report on the design of the sampler and the sampler performance during an initial season of sampling.
