Application Note: Choline in Infant Formula and Adult Nutritionals, a Single Laboratory Validation
8 August 2014
Thermo Fisher Scientific has updated an ion chromatography method to more easily determine total choline (free and bound forms) in 17 samples representing all forms of infant formula, adult nutritionals, and pediatric formulas (powder, ready-to-feed products, and liquid concentrates). This application note demonstrates a simple yet robust approach that decreases sample preparation time while accurately determining choline in these products. The Thermo Scientific™ Dionex™ IonPac™ CS19 column enables simultaneous determination of choline and other cations present in the samples.
