A multistage cryogenic trapping system was used to sample and concentrate organic constituents from turbine engine combustor exhaust. Analyses were conducted by a gas chromatograph-mass spectrometer coupled with a data acquisition system. A 30-minute sample collection, although inadequate for quantitative analysis of individual compounds, showed significant differences in the character of organic compounds in T-56 combustor exhaust between neat fuels and fuels containing organometallic smoke-abatement additives.
