GC-FTIR (Fourier Transform Infrared Spectrometry) of Jet Fuels.

Abstract

The successful interfacing and utilization of fused silica capability Gas chromatography(GC) columns with Fourier transform infrared spectrometry (FTIR) can introduce difficulties not usually encountered with lower efficiency (higher capacity) GC columns. Recognition of these difficulties, however, can lead to refinement of a GC-FTIR detection system which can analyze complete samples with low nanogram detection limits. Chromatography and spectrometric considerations include lightpipe temperature, choice of same introduction, column concentration dynamic range capability, infrared data acquisition rate and spectral S/N ratio. These parameters as they relate to capability GC-FTIR method development are discussed. GC-FTIR 'identification limits' for sixteen model compounds which represent both polar and non-polar functionalities have been established employing optimized chromatographic-spectrometric parameters for complex mixture analysis.
