AB137: Determination of Inorganic and Organic Acids in Apple and Orange Juice Samples Using Capillary IC

Instrument Type: IC

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.

CAN109: Primary Metabolite Analysis of Plant Material Using a Triple Quadrupole MS Coupled to a Monolith Anion-Exchange Column

Instrument Type: ICMS

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.

AN107: Ions (Anions) in Physiological Fluids

Instrument Type: IC

One of the most important applications of IC in clinical chemistry is the analysis of physiological fluids such as urine, plasma, and serum both for inorganic and organic anions and cations. This application note outlines the analysis of physiological fluids using ion chromatography. Part one shows the anion method, the IonPac AS11 is coupled with the Anion Self-Regenerating Suppressor (ASRS) to dramatically reduce eluent conductivity, thus allowing the use of a rapidly increasing hydroxide gradient for the separation of an extensive group of monovalent through trivalent.

TN126: Determination of Organic Acids in Beer Samples Using a High-Pressure Ion Chromatography System

Instrument Type: IC

This Technical Note presents the advantages of the 4 μm particle-size IonPac AS11-HC-4μm column combined with the Dionex ICS-5000+ HPIC system for optimal separation of organic acids and inorganic anions in beer samples using electrolytically generated hydroxide eluent with and without an organic modifier. An ICS-6000 can be used for this application.
