VOC SURVEILLANCE USING EPA'S TRACE ATMOSPHERIC GAS ANALYZER (TAGA) AND ASPECT AERIAL PLATFORM FTIR

Impact/Purpose:

Professional Publication - Environment Canada -Technical Seminars on Chemical Spills

Description:

In a heavily industrialized area in Southeast Texas, EPA atmospheric scientists recently conducted an inter-comparison study of the EPA mobile Trace Atmospheric Gas Analyzer (TAGA) and the ASPECT Aerial Platform FTIR. The TAGA is a mobile air sampling device that is capable of detecting a wide-range of volatile organic compounds in ambient air in the Part per Trillion range. The ASPECT aerial platform FTIR is an aircraft mounted Fourier Transform Infrared detector that includes a 16 band line scanner, thermal imaging camera and digital camera. The ASPECT generally detects most VOCs in the low part per million range although significantly lower detection levels are possible for select chemical species. For this study, fenceline monitoring with the TAGA was conducted while aerial platform ASPECT recordings were conducted. Results of this study will be presented.
