AN1091: Determination of Uronic Acids and Wood Sugars in Wood-Based Hydrolysates: Uronic Acid Method

Instrument Type: IC

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.

AN233: Determination of Galactosamine Containing Organic Impurities in Heparin by HPAE-PAD

Instrument Type: IC

In this application note, the organic impurities in heparin are determined by the HPAE-PAD method using the CarboPac PA20 column following the USP monograph method. This method was repeated using manually prepared eluents and an electrolytically generated eluent, with both eluent preparation options providing data that exceeds the system suitability requirements in the monograph.
