LECO Solutions for Fuels

Comprehensive two-dimensional gas chromatography with flame ionization detection (GCxGC-FID) has proven to be one of the most effective analytical methods for analyzing complex mixtures, allowing for the detailed separation and identification of the hydrocarbons present while providing efficient, high-resolution chromatographic separations.

This application note describes how to use a simple workflow with the LECO Paradigm system to fulfill the requirements of the ASTM D8396 test method to quantitatively determine mass % of total n-paraffins, iso-paraffins, naphthenes, 1-ring aromatics, and 2-ring aromatics using reverse-fill flush flow modulated comprehensive two-dimensional gas chromatography–flame ionization detection (GCxGC-FID). Understanding of bulk composition is crucial for fast-track certification of synthetic aviation fuels as outlined in ASTM D4054, and the more accurate group-type analysis results provided by GCxGC assist with streamlining the acceptance process.

Joining us from University of Southampton, Prof. John Langley, Head of Characterisation and Analytics, Chemistry, present on the latest advancements in renewable and sustainable fuel analysis. Prof. Langley explores how these next-generation fuels introduce new hurdles for quality measurement, requiring innovative hyphenated techniques, including GC-MS and comprehensive two-dimensional gas chromatography (GCxGC-MS). He discusses how GCxGC-MS is pivotal for comparing and analyzing different HVOs, providing clarity on how these tools enable the screening of differences and similarities across various renewable fuel sources.
