Parts-per-trillion determination of trihalomethanes in water by purge-and-trap gas chromatography with electron capture detection

A gas chromatographic method using a purge-and-trap concentrator and electron capture detection to monitor trihalomethanes at the low parts-per-billion and the parts-per-trillion levels is described.
