An analytical method was developed using high performance liquid chromatography with refractive index detection (HPLC-RID) to quantify the concentration of sugars and carboxylic acids including formic acid, acetic acid, propionic acid, butyric acid, lactic acid, glucose, xylose, arabinose, and glycerol in aqueous samples. This list is non-exhaustive as this isocratic method with an acid modified mobile phase is compatible with analysis of many alcohols, small acids, and sugars. This method utilizes a Bio-Rad Aminex HPX-87H Ion Exclusion Column to provide chromatographic separation.
