This work develops methods for the determination of carbohydrates in wood acid hydrolysates using a CarboPac SA10-4μm column, along with a 0.4 µL injection and thicker working electrode gasket. This column contains smaller resin particles, enabling high-resolution, high-efficiency separation, particularly for the rhamnose-galactose that has been challenging to resolve with previous methods. The described method is fast, provides good sensitivity and consistent response, and can be routinely used to determine sugars in wood samples. An ICS-6000 can be used for this application.

The Accelerated Solvent Extraction (ASE) provides a fast and efficient way to extract various biomass samples for sugar analysis to determine sample viability for alcohol production. This application note describes methods for the extraction of sugars from biomass samples using acidified solvents (in-cell hydrolysis) and extracting pre-hydrolyzed samples.

This method shows the direct determination of potential chloride and sulfate in a peroxide-treated denatured ethanol sample, previously published in Application Update 194. In this record, the method is executed on an Integrion IC system.
