Primary ailphatlc amlnes present at trace levels in water samples were converted to imine derivatives using pentafluorobenraldehyde. The derivatlves were extracted into hexane and measured by comblned high-resolution gas chromatography/mass spectrometry using multiple ion mon-Jtoring. The detection limit of thls method for determining amines was 10 ppb for 0.5-mL samples of tap, river, and oll shale process waters.
