Abstract The direct application of gas chromatography with a flame photometric sulphur detector and mass spectrometry to the identification of sulphur heterocycles in coal tar and pitch without the need for prior separation of a sulphur-rich fraction is described. Accurate mass measurement has allowed the assignment of atomic compositions to the sulphur heterocycles with little ambiguity, despite their presence as minor components in a complex aromatic mixture. Single ion chromatograms and… CONTINUE READING
