Abstract:
As routine methods using comprehensive multidimensional gas chromatography (GCxGC) gain acceptance, creative solutions to traditional standardization challenges have emerged. One such solution is the LECO ChromaTOF feature “Classification Correction,” which allows for the simple adjustment of group-type templates between samples collected with different acquisition parameters. Designed to compensate for retention time shifts due to routine GC maintenance such as column trimming or replacement, “Classification Correction” enables the creation of shareable methods from system-to-system and provides valuable time-savings, easing the adoption of newer, more efficient routine GCxGC analyses. This poster shows the utility of the ChromaTOF software package for not only the bulk group-type analysis of alternative aviation fuels, but also the power of detailed hydrocarbon analysis made possible when GCxGC is coupled to time-of-flight mass spectrometry (TOFMS).
