Biomass combustion for heating or energy generation purposes is a significant source of air pollution. Besides gaseous chemicals, respirable particulate matter makes an important contribution. A comprehensive flue gas analysis is required to estimate health risks emanating from these emissions. For this purpose, a mobile analytical instrument was developed which enabled a combined real-time detection of compounds in both the gas and the particle phase. Infrared laser desorption was used for solid samples. Organic molecules were ionized by means of a tuneable UV laser and detected in a...
