Sugar screening using Eurokat column

Applikationsnr.: VFD0190

Sugar screening using Eurokat column

In biorefineries, bacteria and yeast are used for the fermentation of C5 and C6 sugars into bio-ethanol. The by-products from bio-ethanol production are also of value and can be used in other applications. To determine the most suitable column for the analysis of fermentation samples, sugar and sugar alcohol standards were screened using ion exchange Eurokat columns. Measurements using these columns enable the identification and quantification of fermentation broth components, as well as the determination of any impurities that may be present. Screenings using Eurokat Ca, Na, Pb and H columns provided high detection and separation performance for sugars and sugar alcohols. This performance demonstrated that Eurokat columns are suitable for the separation of biorefinery products, as well as for other applications.
