Abstract:
This study explores the use of parallel detection GC×GC to enable both targeted and non-targeted analysis of petrochemicals - with easy-to-use stencils for group-type classification by FID, while the availability of full-range TOF MS spectra enables confident identification of non-target species.
We also demonstrate Tandem Ionisation TOF MS for simultaneous acquisition of both hard and soft EI spectra. Soft EI provides speciation of isomers not possible using conventional 70 eV ionisation – thus unlocking the fine detail of sample composition. The incorporation of soft ionisation also greatly enhances the use of filtering scripts for precise group-type analysis of important chemical classes.
