Determining petrochemical composition by GC×GC–TOF MS/FID: The benefits of flow modulation and Tandem Ionisation

This study demonstrates the performance of a flow-modulated GC×GC system for the analysis of complex petrochemicals, with the INSIGHT modulator providing efficient and repeatable modulation without the need for expensive liquid cryogen.

Diesel analysis by GCxGC-TOF MS/FID

 

Parallel detection by MS and FID (see above) is used to achieve qualitative and quantitative analysis of petrochemicals in a single run, while analyte speciation is aided by Tandem Ionisation for simultaneous acquisition of hard (70 eV) and soft (14 eV) EI data.
