ANALYTICAL METHODS PFOA concentrati on is measured on all production by Gas Chromatograph/Electron Capture Detector (GC/ECD) at the US and European sites and by High Performance Liquid Chromatography (HPLC) method at our Japan site. The Limit of Detection (LOD) for the GC/ED method is 1 ppm . The LOD for the HPLC method is 3 ppm at this time.COMPANY SANITIZED PUBLIC COPY OCTOBER 30 , 200 9 i Fluoropolymers manufactured with PFOA or PFNA. ii Use the following ranges: (1) Zero (2) > 0

– 10 kgs; (3) > 10 kgs

– 100 kgs; (4) > 100 kgs

– 1,000 kgs; (5) > 1,000 kgs

– 10,000 kgs; (6) > 10,000 kgs

– 100,000 kgs; (7) > 100,000 kgs

– 1,000,000 kgs; (8) Over 1,000,000 kgs. iii Concentration should refl ect the concentration of chemical in the product as sold by the reporting company. If the reporting company has information concerning the concentration of chemical in the product as used by others

– for example, as incorporated by dilution into a formulat ion

– that additional information would also be helpful. ivThis value should be expressed as a weighted average concentration and range. v This value should be expressed as a maximum concentration. vi This value should be expressed as a simple (not weighted) average and range.
