Abstract

Selective detectors for gas chromatography (GC) allow one to detect selectively after gas chromatographic separation analytes that either contain certain elements or carry functional groups for which the detector is particularly selective (element-selective detectors). Spectroscopic detectors are a class of selective detectors which, in the ideal case, may even allow the identification of the analytes through acquisition of molecule-specific spectra. Selective detectors often allow the detection, quantitation or identification of analytes even in the presence of complex matrices and may thus significantly improve the selectivity of an analytical method.
