GC Analysis of Xylene Isomers on SLB®-IL60

GC Analysis of Xylene Isomers on SLB®-IL60 - The cresol (methylphenol) isomers are also precursors to many chemicals. This chromatogram of a mix of aromatic and methylphenol compounds was generated using an SLB-IL60 ionic liquid column. Its interaction mechanisms allow the separation of all three xylene isomers, and all three cresol isomers.
