Determination of ethanolamine in gaseous samples by capillary gas chromatography

A procedure for the determination of ethanolamine in gaseous samples was pr oposed. The ethanolamine from the sample was absorbed in a HCl solution (0. 1 mol.l(-1)) and the solution was; evaporated to dryness in a stream of ine rt gas. Derivatizing agent (trifluoroacetic anhydride) was added to the eth anolamine hydrochloride residue. After derivatization, excess of the deriva tizing agent was extracted with an aqueous of ammonia. The resulting ethano lamine derivative was analyzed by gas chromatography on a fused silica capi llary column (1.25 mu m) poly(methylsiloxane)stationary phase. The detectio n limit of 0.2 ng of ethanolamine was achieved.
