AU138: Determination of Ethanolamines in Industrial Waters by Cation-Exchange Chromatography

Instrument Type: IC

Ion chromatography has been successfully used to determine amines in a variety of chemical, petrochemical, and environmental samples. However, analysis of some samples can be hampered by large concentrations of one or more amines, making the determination of trace concentrations of other amines and cations difficult. The selectivity of the IonPac CS11 column with an methanesulfonic acid eluent addresses many of these challenging analyses. This AU describes the setup and performance of this method. In this record we provide the consumables to update this method with eluent generation.

AU126: Determination of Diethanolamine and Triethanolamine in Surface Finishing, Wastewater and Scrubber Solutions

Instrument Type: IC

Alkanolamines are important in the chemical, pharmaceutical, and petroleum industries. Their analysis is also important in metal surface finishing and in wastewater effluents. Ion chromatography (IC) works particularly well for separations of alkanolamines. This application update describes the use of the OmniPac PAX-500 column with Pulsed Amperometric Detection (PAD) to measure alkanolamines.
