Optical detection of ammonia inside a stack: Comparison of different techniques

D’Amato F., Viciani S., Montori A., Lapini A., Fraboulet I., Poulleau J.

Ammonia was measured as a target gas in an artificial stack; Optical detection techniques exhibit different resilience to absorption lineshapes; Target gas absorption widths are sensitive to the concentrations of water and CO2; Direct absorption and derivative detection were compared with respect to calibration; An optical multipass cell was used, completely inside an artificial stack at 140 °C.
