One 2 mL flame-sealed ampule yields up to 2 liters after dilution. Use with EPA Methods 604, 625, 8041, 8270, or other applicable method. Contains a subset of the analytes listed below at 30�200 ?g/L.

NOTE: The assigned value for 4-Methylphenol represents 3-Methylphenol plus 4-Methylphenol combined; as the isomers cannot be distinguished chromatographically or spectrally. Therefore, Waters ERA groups the two isomers together and reports them both as 4-Methylphenol. The Performance Report will only list 4-Methylphenol.
