Abstract:
Petroleum-based fuels contain sulfur compounds, which are controlled to ensure compliance with regulatory specifications and to minimize the catalyst poisoning during refining and in automobile exhaust systems.
Using a detector splitting system, sulfur compounds from fuels are separated by GC and simultaneously sent to an SCD and an MS for detection. This configuration allows for selective and equimolar analysis of sulfur compounds by SCD that would otherwise be overlooked using a TIC from the GC-MS. The mass spectrometer and associated spectral library can then be used to positively identify sulfur compounds by using known retention times from the SCD data.
