MSI HPLC2000.1-KT

A key measurement is the residual sugar and ethanol concentrations in the fermentation broth. Fuel ethanol facilities use High-Performance Liquid Chromatography (HPLC) as the technique of choice to monitor the ethanol fermentation process. HPLC permits detailed monitoring of the complete cycle, including conversion of the sugars to ethanol and ethanol breakdown to acetic acid. 2 ampoules of each A, B and C.
