摘要

Uncontrolled emissions from an asphalt coating operation were performed using Extractive FTIR spectroscopy. Signifiant sampling and spectral analysis challenges were encountered due to the complex effluent composition that included several HAPs and numberous volatile and semi-volatile organics. The semi-volatile species included high molecular weight aliphatic hydrocarbons that could condense in the heated sampling system and continue to be detected at low levels for an extended period. Sampling system contamination was minimized by limiting samping time and purging between test runs. On-site QA/QC procedures included local, system, and dynamic matrix spiking calibrations with Methanol, 1,3-Butadiene, and p-Xylene.
