The Colorado Department of Public Health and Environment (CDPHE) is working with Entanglement Technologies to gain understanding and data on refinery emissions and their temporal and spatial variations in the Centennial State. Using AROMA-VOC, the CDPHE will be able to measure key hazardous air pollutants (HAPs) frequently used in the petrochemical industry such as BTEX and 1,3-butadiene down to part per trillion detection limits in both a long-term fixed study and a mobile, large geography assessment. The highly stable analyzer core of AROMA-VOC facilitates long-term remote deployments with fully remote instrumentation operation for the fixed monitoring portion of the campaign. The mobile monitoring campaign, using the same AROMA-VOC, will explore spatial variations of the hazardous air pollutants, and will allow the CDPHE to gather critical data over hundreds of miles on the potential exposures of these pollutants to nearby communities.
