The compounds are continuously collected into a thin film of deionized water flowing down the inner wall of the cylindrical wet effluent diffusion denuder. The concentrate is analysed by gas chromatography. Detection limits of alcohols and ketones are as low as 1mikrog/l (GC-flame ionization detector) and/or 1 ng/l (GC-MS). This technique could be applicable for the continuous monitoring of ppb (v/v) level of both and ketones in the air.
