GB/T 36058-2018Method for analysis of forestry biomas—Determination of insoluble saccharides content (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This standard specifies the terms and definitions, principles, reagents and materials, instruments and equipment for the determination of insoluble sugar content in forestry biomass raw materials. Sample preparation, test procedures, test data processing, precision requirements, and test reports.

This standard applies to the determination of insoluble sugar content in forestry biomass raw materials.

When the injection volume was 20 µL, the detection limit (S/N >= 3) of the method was. glucose 8 mg/L, xylose 14 mg/L, Arabinose 28 mg/L, galactose 10 mg/L, and mannose 16 mg/L.

3 Terms and definitions

The terms and definitions defined in GB/T 30336-2013 and the following apply to this document. For ease of use, the following is repeated Some terms and definitions in GB/T 30366-2013.

4 Principle

The insoluble sugars in the forestry biomass feedstock can be converted to the corresponding monosaccharides by two stages of sulfuric acid hydrolysis. High performance liquid chromatography (HPLC) After the monosaccharide content was measured, the insoluble sugar content in the forestry biomass material was calculated.
