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.

This application demonstrates the analysis of inorganic anions and anions of organic acids in waste liquor from wood extracts. The sample matrix and the contaminant were removed from the components of interest using an IonPac NG1 column as an additional guard column. This application requires an autosampler equipped with 10-port valve. With this configuration, IonPac NG1 column is placed in line with the analytical column, while a second column rinsed in counter flow direction with acetonitrile/water, followed by a conditioning step using sodium hydroxide.

Wood chips are used for producing paper and are also contained in waste deposits. It is important to know the halogen contents of wood chips for impurity management in paper production and for environmental assessment in waste materials. By using a combustion ion chromatography (CIC) system consisting of the automatic quick furnace AQF-2100H and an ICS-1600 ion chromatograph, the concentrations of halogens and sulfur can be determined accurately and quickly.

Wood, grass, and other lignocellulosic biomass are emerging as the preferred sources for biofuel and biochemical production. Compositional analysis of plant derived material is crucial for maximizing the yield of biofuel production. This record shows an HPAE-PAD Method that uses the Dionex CarboPac PA200 column to determine uronic acids in wood hydrolysates.
