Selective Detection in Gas Chromatography.
Abstract
High-resolution gas chromatography (HRGC) is capable of separating a very complex hydrocarbon liquid such as jet propulsion fuel into nearly all of its individual components. However, there is no guarantee that what appears to be a single chromatographic peak is in fact a single fuel component. The method of detecting these HRGC eluents is very often the flame ionization detector (FID), a very sensitive and universally responding hydrocarbon detector. Neither the separating power of HRGC, or the sensitivity of the FID, however, lend information as to the identity of the eluting component. The need to specifically identify HRGC eluents, especially those containing heteroatoms such as nitrogen, sulfur, phosphorus, oxygen, halogens and some materials has been well-documented. The purpose of this report is to review the progress in the area of selective gas chromatographic detectors and to recommend selective detectors for use in the HRGC analysis of jet propulsion fuels. This report will present 24 different selective gas chromatographic detectors. These detectors, while not all directly applicable to the HRGC analysis of jet propulsion fuel, all show the concept of selective detection in gas chromatography. The applicability of these detectors to jet propulsion fuel analyses is determined from a comparison of their complexity and cost versus their effectiveness as high-resolution gas chromatographic detectors.
