Rapid Analysis of Sugars, Organic Acids, and Alcohols

Bioethanol production process requires frequent rapid analyses of sugars, organic acids, and alcohols to monitor the proper operations of biomass fermentation steps. There are seven main target analytes: two maltooligosaccharides, maltotriose and maltose, its constituent sugar, glucose, and the final products, ethanol, lactic acid, acetic acid, and glycerol.

In this work, we used a Shodex™ SUGAR™ SH1011 8C for the analysis of those seven target components. Shodex™ SUGAR™ SH1011 8C is a 10-cm rapid analysis column filled with rigid styrene-divinylbenzene copolymer base material. The strong cation exchange gel works to provide a mixed mode of size exclusion and ion exclusion chromatography, which is suitable for simultaneous analysis of various sugars and organic acids. The analysis time of Shodex™ SUGAR™ SH1011 8C is one thirds of our regular 30-cm analysis column, Shodex™ SUGAR™ SH1011. Thus, it is well suited for rapid analyses of sugars and organic acids.
