Abstract:
Reference aviation and diesel fuels were tested along with gravimetric standards on a reverse fill-flush GCxGC-FID system following ASTM D8396, demonstrating robust hardware and simplified method parameters that reliably provide full transfer of analytes from the primary to secondary GC column. Additional sample characterization utilized a prototype GCxGC-TOFMS/FID instrument equipped with a novel splitter design ensuring a consistent split ratio between the MS and FID detectors to avoid erroneous area percent determinations and a novel peak alignment algorithm simplifying identification of FID peaks using corresponding MS spectra to assist in drawing regions for more accurate group-type quantitation of chemical classes.
