This method describes the determination of the carbohydrate composition in wood pulp samples. This method makes it possible to determine concentrations of individual anhydrous monosaccharides down to 1 mg/g oven-dry pulp.
Abstract
Overview
ISO 21437:2020 specifies an analytical method for determining the carbohydrate composition of wood pulps. The standard quantifies the five principal neutral monosaccharides - - in pulp samples, with detection down to . The procedure is based on a two‑step followed by chromatographic determination of the released monosaccharides.
