AN72609: Using Ion Chromatography with Electrospray Ionization Mass Spectrometry for the Determination of Cations and Amines in Alkanolamine Scrubbing Solutions: MDEA Be the first to rate this application


Alkanolamines, such as methyldiethanolamine (MDEA), diethanolamine (DEA), and ethanolamine (EA), are used to neutralize the sour gas impurities. The amine solutions are monitored for concentrations of alkanolamine and inorganic cations to maintain neutralizing capacity and to minimize salt-induced corrosion, respectively. In this application note, µg/L to mg/L concentrations of sodium, ammonium, and calcium in high concentrations (mg/L to percent) of alkanolamines are determined by IC-MS on the Integrion IC and ISQ EC mass spectrometer. See also TN72611 for configuration.
