Mhen converted to ppb C8, the result of 1.3 ppb 1984, but considering becomes 1.9 Ppb. how close we are This result is higher to the detection limit than those from of the test, the difference is probably not significant.

E44875) Five samples of water have been analyzed for perfluorooctanoale (C8) by electron capture gas chromatography. Method ES-567 was used with the f o l l o w i ng co m nc odi ent ficatio ration ns of E p s ar amp fluo le ro size w decano as ate 1 0 g; inte r lyo nal philizatio standard n w w as a s d "18-20 ecrease d 10 hours; fold. Spiked standards at concentrations of 0.4, 0.5, 0.9, 1.0 detectable peak was observed for and 1.9 ppb 0.4 ppb and we were examined. A reproducible have used this SB our detection limit. No C8 peak was detected in the spiked standards <.4 ppb. For the quantitationi we had linear calibration curves over The samples were freeze dried, derivitized, and the range of 0.4 to 1*9 analyzed in duplicate, ppb. The results? are expressed as ppb fluoride where ppb P ' 0.688 x ppb pertluorooctanoate. The results are given in the attached table, questions, don't hesitate to call.
