Notes:
Summary In a series-coupled system of two capillary columns with different polarity, a controlled overlapping of sulphur-containing and sulphur-free compounds can be achieved by means of different mid-point pressure settings. By means of this selectivity tuning it is possible to measure exactly the quenching of the flame photometric detector signal for a sulphur compound coeluted with an excess of a sulphur-free compound. With the example of a complex sample it is shown that, with a suitable system of columns, selectivity tuning can give quench-free FPD chromatograms or chromatograms with quench-free regions.
