An HPLC-ESI-QTOF method to analyze polar heteroatomic species in aviation turbine fuel via hydrophilic interaction chromatography through statistical analysis of mass spectral data

• HILIC-ESI-QTOF method analyzes polar heteroatomic species. • Method enables high-fidelity data for chemometric analysis. • Identified N-compounds linked to deposit formation via FC. • Three trends relate N-species to deposit formation identified. • DBE and carbon number linked to deposit formation. Aviation turbine fuel, a complex mixture of thousands of compounds, contains small amounts (/=4], 2) decreased deposit at low carbon numbers and increased deposit at high carbon numbers (DBE = 1–3), and 3) increased deposit for specific compounds while others showed no change (DBE = 0). These findings provide valuable insights, confirming previous research, uncovering new information, and highlighting areas for future investigation.
