Determinations of organic acids in fruit juices are used by the beverage industry for flavor characterization, identification of spoilage, identification of adulteration by a less costly juice, and product labeling. In this study, inorganic anions and organic acids in diluted filtered apple and orange juice samples were determined on a Dionex IonSwift MAX-100 anion-exchange column using electrolytically generated hydroxide gradient from 0.1–65 mM KOH over 25 min at 15 μL/min.

A platform using Dionex ion chromatography (IC) coupled to triple quadrupole mass spectrometry (MS) was developed to measure various metabolites in Brassica napus seeds. The IC tandem mass spectrometry (IC-MS/MS) technique provides a good tool to identify and quantify metabolites in a complex matrix.

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.

This application brief describes the determination of counter anion chloride in a drug for type 2 diabetes using the Thermo Scientific Dionex ICS-5000 capillary IC system and Dionex IonSwift MAX-100 capillary column. The Eluent Generation Cartridge lasts 18 months under this condition in continuous operation mode and each analysis is less than 8 min.

The determination of common inorganic anions in drinking water is one of the most important applications of ion chromatography (IC) worldwide. This application brief describes the fast determination of inorganic anions in drinking water samples with the Dionex ICS-5000 capillary system using the Dionex IonSwift MAX-100 column. The high pressure capability of this system facilitates higher sample throughput by simply increasing the flow rate of analysis.
