Abstract: | Summary This paper summarises experience gained at the British Petroleum Limited Research Centre, Sunbury-on-Thames, with sulphur
selective gas chromatography (GC) detectors. A single flame photometric detector (SFPD) has been in use for three years for
research and routine applications. Three areas of interest are described demonstrating in turn different characteristics of
the detector. Firstly, a determination of trace levels of individual organo-sulphur compounds in the 15–65°C cut of crude
oils illustrates the complexity of using an SFPD in a rigorously quantitative manner. Secondly, the use of an SFPD as a qualitative
tool for the comparison of the sulphur distribution of crude oils up to the temperature limit of GC is cited. Finally, a third
section describes the properties of a dual flame photometric detector (DFPD) which are compared and contrasted with those
of the SFPD. |
