AN123: Determination of Inorganic Anions and Organic Acids in Fermentation Broths

Instrument Type: IC

Fermentation broths are complex mixtures of nutrients, waste products, cells and cell debris, and desired products. Fermentation monitoring is important for many industries because carbon sources and metabolic by-products can impact the yield of the desired products. This application note describes the use of two different anion-exchange columns, IonPac AS11 and IonPac AS11-HC, with suppressed conductivity detection, to analyze common organic and inorganic anions in yeast and bacterial fermentation broths.
