Determination of High Sugar Concentrations in a Malbec Wine Sample Using a Compact Ion Chromatography System

Instrument Type: IC

This record demonstrates the determinations of glucose in a 100-fold diluted Malbec wine sample by HPAE-PAD. Typically samples with g/L concentrations require > 10,000-fold dilutions to remain in the linear range of the very sensitive HPAE-PAD technique. However, this method, demonstrated on the Integrion RFIC system, uses a 0.4 µL internal injection loop with the High Concentration Carbohydrate Analysis Kit to extend the linearity from low mg/L to g/L concentrations. A wood hydrolysate application using this technique is attached for reference.

Determination of High Sugar Concentrations in a Basalmic Vinegar Sample Using a Compact Ion Chromatography System

Instrument Type: IC

This record demonstrates the determinations of glucose and fructose in a 100-fold diluted basalmic vinegar sample by HPAE-PAD.
