Analysis of Organic Acids and Anions in Fermentation Broth
17 September 2012

In this poster a simple and rapid capillary electrophoresis method for the determination of anions and organic acids in fermentation broth, using the Anion Analysis kit from Beckman Coulter, is described. This method utilizes a dynamic capillary coating and indirect UV detection to provide resolution of 4 anions and 11 organic acids that contribute to overall product quality in beer. Both final product and in-process beer samples were evaluated for anions and organic acids.
