Methods for sampling, handling and measuring emissions of particulates, hydrocarbons, carbon monoxide, carbon dioxide, oxides of nitrogen and oxygenated compounds in the exhaust of aircraft turbine engines were evaluated in a cooperative experimental program conducted by industry and government at the Naval Air Propulsion Test Center in September, 1969. Non-dispersive infrared (NDIR) instruments and a Fisher chromatographic partitioner were both well suited for measuring CO and CO2. Some additional development is needed in NDIR instruments and the phenol disulphonic acid (PDS) method for measuring NOx and in the 3-methyl-2-benzothiazolinone hydrazine hydrochloride (MBTH) method for measuring oxygenated compounds.
