' , . Summary
.'.'.
.".
Seven solid media samples were received by Centre Analytical Laboratories, Inc. (dba Exygen
Research) (Exygen) from DuPont Corporation. The media represent samples of air collected on
OVS tubes. Please see Table 1 for a completed listing of samples received and field air volumes
collected. Results are not reported for sample WWK-A-AMS2-E10 because of sampler
malfunction.
The samples were analyzed for Perfluorooctanoic Acid (C8 Acid) using liquid chromatography / mass spectrometry (LCMS). The method employed is entitled "Method of Analysis for the Determination of Perfluorooctanoic Acid (PFOA) in OVS Airtubes by LCMS" (James Miller, Exygen Research, February 17, 2003).
The OVS tubes were separated into three fractions for specific fluorochemical analysis. 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 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.

Please note: One control sample was spiked with each perfluorooctanoic acid to give a final concentration of 500 pp
through the tube at a rate of 1-liter per minute for one hour (60 liters of air). The fractions were separated and analy
acceptable range for control recovery is 75-125%.
