✦ Synopsis

A method has been developed for the-direct determination of alkyl amine hydrochlorides in aqueous solution, The method involves conversion of the hydrochloride salts to the free amines in the injection port of a gas chromatograph, followed by chromatographic separation and detection of the free amines. Standard response curves for each of a group of thirteen amine hydrochlorides have been determined. These curves cover a range from approximately 17 to 250 parts per million of the amine hydrochloride in 'aqueous solution. Primary, secondary and tertiary aliphatic amines, as well as isomeric amines in the series methyl through pentyl have been tested. A single column system used at three different temperatures provides for the independent determination of any or all of the thirteen amine hydrochlorides tested.
