AN72808: Determination of Organic Acids in Herbal Beverages using a Compact Ion Chromatography System Coupled with Mass Spectrometry
DescriptionThis work uses IC with suppressed conductivity and mass spectrometry detection for organic acid determinations. This dual detection approach increases the information available from the sample. Samples were separated with a high-resolution Thermo Scientific™ Dionex™ IonPac™ AS11-HC-4μm column set using a Thermo Scientific™ Dionex™ Integrion™ HPIC™ system with suppressed conductivity detection, and an ISQ EC MS. Co-eluting organic acids can be accurately quantified with mass spectrometric detection, eliminating the need for the addition of methanol to the hydroxide eluent to enhance separation.
