The Development of a Novel Dilution Technique for a Sub-micron Particulate Characterization
Large concentrations of sub-micron particulates are a severe problem when sampling jet engine emissions. This paper will describe the development and characterization of a novel particulate filter system, to be employed during ground sampling of aircraft engine particulate emissions. Tube/filter assemblies were fabricated and their dilution properties were characterized. Dilutions > 30:1 have been achieved and dilution factors of up to 5000: 1 have been employed using these devices during Cloud and Aerosol Science Laboratory field programs. This unique technique has proved sufficiently reliable that it has had immediate application in several of CASL's externally sponsored environmental field programs. This paper specifically addresses the development and characterization of the diluters.
