Abstract The article describes an automatic gas chromatograph with a flame photometric detector (GC-FPD) that samples and analyzes hydrogen sulfide (H2S) and carbonyl sulfide (COS) at 30-sec intervals. Temperature programming was used to elute trace amounts of carbon disulfide (CS2) present in each injection from a Supelpak-S column in a single peak at the end of 15 min runs. The system was used to study the high-temperature fuel-rich sulfur capture reactions of H2S and COS with injected calcium oxide (CaO) sorbent, necessitating the near continuous measurement of these gaseous sulfur species. The H2S concentration ranged from 300 to 3000 ppm, and the COS from 30 to 300 ppm. The system was also used to monitor sulfur dioxide (SO2) levels under fuel-lean conditions: results compared very closely with SO2 measurements made simultaneously with continuous ultraviolet (UV) SO2 instrumentation.
