Abstract:
Described is a High-Performance Anion-Exchange chromatography with Pulsed Amperometric Detection (HPAE-PAD) for accurate determination of common sugars in biomass such as acid-hydrolyzed corn stover. The method uses the Dionex CarboPac SA10 column with electrolytically generated hydroxide eluent, enabling fast analysis of the biofuel sugars. The method has a linear range suited for handling high concentration samples with minimal sample treatment, high precisions, and acceptable recoveries. The disposable gold working electrode provides consistently high detector response, assuring greater instrument-to-instrument and lab-to-lab reproducibility. The HPAE-PAD and Dionex CarboPac SA10 column can be adopted for on-line monitoring of sugar levels in biomass applications.
