Application Proof Note: Determination of High Sugar Concentrations in a Scotch Liqueur Sample Using a Compact Ion Chromatography System

This application proof note demonstrates the determinations of glucose, fructose, and sucrose in a 100-fold diluted alcoholic beverage sample by HPAE-PAD. Typically, samples with g/L concentrations require greater than 10,000-fold dilutions to remain in the linear range of the very sensitive HPAE-PAD technique. However, in this proof note, the method is performed using a Thermo Scientific ™ Dionex ™ Integrion ™ RFIC ™ system eqipped with a 0.4 μL internal injection loop and the Thermo Scientific ™ High Concentration Carbohydrate Analysis Kit 1 to extend the linearity from low mg/L to g/L concentrations. A wood hydrolysate application using this technique is available for reference. 2
