AN73030: Alkanolamine Determinations in Neutralizing Amines Samples with Improved Separation Technology Be the first to rate this application


Natural gas (methane) is an important energy resource, accounting for 29% of the total energy consumed in 2017. Amine gas treatment typically uses percent concentrations of alkanolamines to neutralize the sour gas impurities. This application note demonstrates an alternative method for the separations of μg/L to 25 mg/L of inorganic cations and ammonium, and μg/L to 1250 mg/L concentrations of alkanolamines in 1000-fold diluted neutralizing amine solution sample using a 0.4 μL internal sample loop and a KOH gradient on a Dionex IonPac CS20 column.
