ARiaG-oom VAPOR PRESSURE /fc-2. TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as PFO S or FC-95. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-, potassium salt, CAS # 2795-39-3) Remarks: The test substance is a white powder. Sample was taken from 3M lot number 217. Sample was stored under ambient conditions prior to testing. Purity determined to be 90.49% by LC/MS, 1H-HMR, 19FNMR and elemental analyses techniques. METHOD____________________________________________________ Method: OECD 104, U.S. EPA O PPTS 830.7950 GLP (Y/N): Yes Year completed: 1999 Remarks: Determination of the vapour pressure was done by using the Spinning Rotor Gauge method. RESULTS Vapor Pressure: 3.31X1 O'4 Pa Temperature C: 20C Decomposition (yes/no/ambiguous): No Remarks: The measured vapour pressure was repeatable. CONCLUSIONS Remarks: The vapor pressure of the test substance was determined to be 3.31X1 CF* Pa at 20C using the spinning rotor gauge method. Submitter: 3M Company, Environmental Laboratory, P.O.
