AB135: Determination of Anions and Organic Acids in Brewed Coffee Samples Using Capillary IC Be the first to rate this application

anions organic acids brewed coffee


The characteristic aroma, acidity, and flavor of a coffee are attributed to the inorganic anions, organic acids, chlorogenic acid, and monosaccharides content. In this study, inorganic anions and organic acid anions in caffeinated and decaffeinated brewed coffee samples are separated within 20 min by anion-exchange chromatography on a capillary Dionex IonSwift MAX-100 (0.25 × 250 mm) column set using a gradient of potassium hydroxide eluent at 12 μL/min.
