An improved method for determining total galactooligosaccharide (GOS) content in food and supplements using high performance anion exchange chromatography with pulsed amperometric detection is described.

Uncovering the benefits of a system that hyphenates ion chromatography, titration, and direct measurement, in environmental analysis of water samples.

Sulphite is a preservative added to a vast range of foods and beverages to prevent browning or oxidation. Some individuals are sensitive to sulphite additives and may experience a range of allergic reactions. Therefore, both the U.S. Food and Drug Administration (FDA) and European Union (EU) laws require that the presence of sulphites be declared on food labels when the concentration exceeds 10 mg/L. Several analytical methods exist to measure sulphite in food and beverages, however, they suffer from repeatability issues, and can be quite cumbersome to perform. A patent has been filed for an innovative, fast, and accurate ion chromatographic (IC) method based on direct current (DC) mode electrochemical detection. This article explains more.
