(dba Exygen Research) (Exygen) from DuPont Corporation. The media represent Samples of air collected on r OVS tubes. Please see Table 1 for a completed listing of samples received and field air volumes 1 collected. Sample WWK-A-AMS3-E7 had.sampler problems during collection. No results are reported for this sample. ^ The samples were analyzed for Perfluorooctanoic Acid (C8 Acid) using liquid chromatography I 7 mass spectrometry (LCMS). The method employed is entitled "Method of Analysis for the f Determination of Perfluorooctanoic Acid (PFOA) in OVS Airtubes by LCMS" (James Miller ; Exygen Research, February 17, 2003). r The OVS tubes were separated into three fractions for specific fluorochemical analysis. I Fraction A consisted of the filter, backing material and plastic ring. Fraction B contained the first bed of XAD resin and the PUF backing. Fraction C contained the second bed of XAD y resin and PUF backing. Fractions A and B were extracted with 1 mL of methanol. Fraction C ^ Was not analyzed but saved for possible future analysis. Perfluorodecanoic Acid (CIO Acid) , was added as a surrogate spike to each fraction prior to extraction. | Instrument operating conditions can be found at the beginning of each analytical run. Raw instrument data is given in Appendix A. Chain-of-custody information can be found in | Appendix B.
