This method is for determining saccharides in aqueous solutions by high performance liquid chromatography (HPLC). Specific saccharides typically quantitated are tetrasaccharides (DP4+) and unresolved higher polysaccharides; maltotriose including other unresolved trisaccharides (DP3); maltose, maltulose plus other unresolved disaccharides; glucose; mannose plus sorbose; fructose; and psicose. The lower limit of quantitation for an individual component in the aqueous solution is typically 0.01 mass-%.
