Description:

EPA is developing advanced open-path and cell-based optical techniques for time-resolved measurement of priority hazardous air pollutants such as formaldehyde (HCHO). Due to its high National Air Toxics Assessment risk factor, there is increasing interest in continuous measurement of HCHO in the low parts per billion range using robust and cost-effective monitoring technology. Measurement of HCHO using optical spectroscopy has several inherent operational advantages including direct atmospheric sampling, high time resolution, permanently recorded spectra, and no laboratory analysis costs. Additionally, optical techniques generally lend themselves to long-term automation strategies and remote operation necessary for continuous monitoring applications. In addition to the cell-based quantum cascade laser spectroscopy approaches, EPA is investigating modified versions of Fourier Transform Infrared spectroscopy for automated measurement of low-level HCHO.
