LECO NA - Jet Fuel Analysis by High Resolution TOFMS

August 7, 2013

In this application note, the combination of chemical ionization (HR-CI) and standard electron ionization (EI) on the Pegasus GC-HRT (High Resolution TOFMS) provides an unparalleled analysis tool for jet fuel characterization. In particular, for labile branched chain alkanes, the confirmation of intact molecular ions is facilitated by HR-CI. Characterization of these branched species is vital to jet fuel producers.
