Abstract:
D5769 for Benzene, Toluene and Total Aromatics in Finished Gasoline by Gas Chromatography/Mass Spectrometry is the ‘gold’ standard method required for certification of gasoline in many countries and regions of the world. The method challenges detection limits as well as linear ranges of the components of interest in GCMS. Also, as changes in the composition of gasoline continue to evolve, this further challenges the GCMS instrumentation to comply with the method. The new Thermo Scientific ISQ7610 MS together with the new 1610 GC provides a fresh approach to overcoming these challenges. The new Extended Dynamic Range Electron Multiplier used in the ISQ7610 provides the range necessary for the method without compromising any required MS hardware or operational parameters. Data will be presented and discussed demonstrating full compliance to the method using the Thermo Scientific GCMS. All aspects of the method specifications including sensitivity, resolution, ion check tests, calibration, and reference material compliance tests will be presented. In addition, the analysis of an ASTM D5769 ILS sample will be presented demonstrating excellent results.
