A sensitive automated procedure for the determination of glucuronic acid.

A newly automated method for the detection of uronic acids, particularly glucuronic acid is described. Data showing the limitations of this method are also presented. The advantages of the method are: (1) greatly increased sensitivity compared to the carbazole methods and increased range; (2) lowered interference from other sugars, proteins and salts; (3) variability to allow small sample volumes and/or continuous flow; (4) a more stable color reagent solution.
