General description

o-Xylene is an environmental pollutant belonging to the class of volatile organic compounds. It is emitted from a variety of sources including adhesives, degreasing agents, combustion products of wood and fuels, industrial paints, aerosols, etc.

Application

o-Xylene may be used as an analytical reference standard for the quantification of the analyte in occupational environmental samples and aqueous samples using gas chromatography technique with different modes of detection.
o-Xylene may be used as a model contaminant for investigating the safe use of products based on recycled fibers in contact with foodstuffs via measuring its uptake by the fiber material and evaluating its migration behavior onto tenax.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

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.
