    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.[1]

    Application

    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.[2]
    o-Xylene may be used as an analytical reference standard for the quantification of the analyte in occupational environmental samples[3] and aqueous samples[4][5] using gas chromatography technique with different modes of detection.
    Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
