Abstract
Comprehensive gas chromatography is an excellent technique for separating complex mixtures. If, however high-boiling compounds such as polychlorinated biphenyls have to be analysed, proper adjustiment of the temperature of the modulator turns out to be very important in maintaining the performance of the system. It is shown that miniaturisation of the column-to-modulator coupling, adequate selection of the modulating conditions and, for halogenated compound mixtures, the use of a micro electron-capture detector, can solve experimental problems previously encountered with high boilers.
