Development of an Infrared Spectrophotometric Method for the Analysis of Jet Fuel Using a Loop Calibration Technique

A whole body inhalation study of combined jet fuel vapor and aerosol necessitated the development of a method for preparing vapor standards from the neat fuel. Due to the complex mixture of components in jet fuel, and the selective partitioning between aerosol and vapor, a novel method was needed to prepare vapor only standards for the calibration of infrared spectrophotometers and a gas chromatograph. A re-circulating loop system was developed which provided vapor only standards whose composition matched those seen in an exposure system. Comparison of nominal concentrations in the exposure system to those determined by infrared spectrophotometry and gas chromatography were in 8O%-99% agreement.
