N2 - Octanol-air partition coefficients (KOA) for three fluorotelomer acrylates (6:2 FTA, 8:2 FTA, 10:2 FTA), two perfluoroalkyl sulfonamides (n-methyl perfluorooctane sulfonamide (MeFOSA), n-ethyl perfluorooctane sulfonamide (EtFOSA)), and two perfluoroalkyl sulfonamido ethanols (n-methyl perfluorooctane sulfonamido ethanol (MeFOSE), n-ethyl perfluorooctane sulfonamido ethanol (EtFOSE)) were determined over a temperature range from (278 to 313) K using a modified generator column method. The KOA values were calculated as the ratio of the target analyte concentrations in octanol to the target analyte concentrations in octanol saturated air. Calibrated log KOA values at 298 K ranged from 4.5 (6:2 FTA) to 6.7 (EtFOSE). Log KOA values decreased with increasing temperature and increased in the order of 6:2 FTA, 8:2 FTA, 10:2 FTA, MeFOSA, MeFOSE, EtFOSA, EtFOSE. The combined uncertainty of the method applied ranged from 5.1 % (6:2 FTA) to 17.6 % (MeFOSA). The relative extended uncertainty (P ) 95 %) ranged from 11.6 % (6:2 FTA) to 39.8 % (MeFOSA), respectively.
