JET ENGINE EXHAUST ANALYSIS BY SUBTRACTIVE CHROMATOGRAPHY

This report describes the further refinement of a method for the sampling and analysis of organics in jet engine exhaust by chemical classes. Details for the selection, construction, and evaluation of the combination sorbent (Tenax-GC/Ambersorb XE-340) sampling system are given along with the rationale and operational parameters for the subtractive chromatography system that produces the organic class analysis. The significant improvements incorporated into both the sampling and analytical systems compared with previous systems used in a jet engine exhaust study of March 1975 are discussed. The capabilities of the system are illustrated by the analysis of actual jet engine exhaust samples from a J85-5 engine using JP-4 and an alternate fuel blend that simulates the higher aromatic content expected from shale and coal-derived fuels.
