This book gives a comprehensive, up-to-date review of all selective detectors used in combination with gas chromatography. For each detector, the historical background, design and principle are described, and the working parameters affecting the detector performance are analyzed critically and in detail. The analytical possibilities of the detectors and the main characteristics such as sensitivity, noise and minimum detectability are discussed. All the selective detectors that are currently used are discussed in detail. Combinations of GC with other techniques such as plasma emission spectroscopy, atomic absorption spectrometry, ion-selective electrodes, piezoelectric sorption detector, mass spectrometry and infrared spectroscopy are discussed briefly.Chromatographers and users of gas chromatographs, especially in the field of environmental protection, agriculture, clinical chemistry, and toxicology will find the book useful to their work. Institutes and organisations dealing with analytical chemistry will also find it of interest.

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. Keywords: Ionization detectors, Fourier, Electron capture, Photoionization, Catalytic ionization, Infrared, Atomic absorption spectrometry, Ultraviolet.

Spectrometric detection systems for gas chromatography (GC) based on gas phase ultraviolet absorbance and fluorescence measurements have been developed and evaluated in this research. Polynuclear aromatic compounds (PNAs) are selectively detected by these systems. Limits of detection for PNAs range from 4 ng to 90 ng for absorbance determinations, and from 3 ng to 400 ng for fluorescence determinations made at a fixed waveband. The spacial design and optical components have been carefully selected to be compatible with hightemperature gas-phase measurements (ca. 250°C) while preserving the resolution of the chromatographic separation and enhancing the sensitivity of the multimode spectrometric determinations. Vapor-phase determinations of GC eluates are made directly as they leave the GC column in specially designed, heated flow-through detector cells with low volume and dead space. A long pathlength cell of 167 mm was used to enhance the sensitivity of the absorbance measurements. High-temperature, quartz fiber optic bundles transmit light to and from the detector cell, thus thermally isolating optical components. There are two configurations for these GC detection systems, each advantageous for either quantitative or qualitative determinations, respectively. In the first, waveband selection is accomplished via optical filters. These simple and compact systems are particularly suited to precise and sensitive determinations of polynuclear aromatic compounds. The sensitivity and selectivity of the absorbance and fluorescence measurements vary with individual compounds. These differences also provide some qualitative information about eluates. The second detection system configuration provides repetitive UV spectral information of GC eluates. This computer-controlled system scans a modified Czerny- Turner monochromator and can acquire up to two 62-nm spectra of eluates per second. Spectral information thus obtained may be used for identification purposes and to locate unresolved GC eluates. After compounds have been separated and identified, fixed waveband spectrometric data acquired at an absorption maximum may be used to determine concentrations.
