Introduction
This Application Note demonstrates the repeatability of a flow-modulated GC×GC–TOF MS system for the analysis of complex petrochemicals. The analytical approach described pushes the boundaries of hyphenated systems by simultaneously providing three information-rich datasets for each acquisition – namely, robust quantitation by FID, untargeted screening by TOF MS with electron ionisation (EI) at 70 eV, and confirmatory identification by TOF MS with soft EI.
