摘要

This method provides procedures for the determination of nitrosamines in finished drinking water. The method may be applicable to untreated source waters and other types of water samples, but it has not been evaluated for these uses. The method is applicable to nitrosamines that are efficiently partitioned from the water sample onto a solid phase extraction (SPE) sorbent, and sufficiently volatile and thermally stable for gas chromatography.
