AN1152: Determination of Carbohydrates in Kombucha Using HPAE-PAD

Instrument Type: IC

The method uses the Thermo Scientific™ Dionex™ CarboPac™ PA20 column with electrolytically generated hydroxide eluent and a 15 mil gasket for the gold working electrode to separate and detect glucose, fructose and sucrose in kombucha.

Determination of High Sugar Concentrations in a Flavored Rum Liquor Sample Using a Compact Ion Chromatography System

Instrument Type: IC

This record demonstrates the determinations of glucose, fructose, and sucrose in a 100-fold diluted flavored rum alcohol sample by HPAE-PAD. Typically samples with g/L concentrations require > 10,000-fold dilutions to remain in the linear range of the very sensitivie 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 Sparkling Wine Sample Using a Compact Ion Chromatography System

Determination of Sugars in Soft Drinks Using a Compact IC System

Instrument Type: IC

Excess sugar consumption is tied to poor health outcomes. Nutritional information including sugar amount is required in the Nutrition Facts label for all pre-packaged foods and drinks by The Nutrition Labeling and Education Act. A high-performance anion exchange method with pulsed amperometric detection (HPAE-PAD) has been developed to accurately determine the sugar concentrations. This record shows the determination of sugars in soft drinks using the Thermo Scientific Dionex Integrion system. This system allow fast determination of sugars with no eluent preparation or sample derivatization.
