Executive Industry Relevance

Accurate detection and quantification of trace nitrogen compounds in complex fuel matrices is critical for assessing fuel stability and performance during storage and use. The GCxGC-NCD method provides compound class-level nitrogen characterization with minimal sample interference, enabling reliable data for fuel formulation decisions. This approach supports mechanistic de-risking in early-stage fuel development by linking specific nitrogen species to stability outcomes.
