ASTM E3417-24A - Standard Test Method for Determination of Cellulose/Hemicellulose-Derived Glucan and Galactan Content in Solid Corn Biomass Samples

1.1 This procedure can be used to quantify the cellulose/hemicellulose-derived glucan and galactan (CHDGG) content in corn biomass samples that also contain varying levels of starch-derived and yeast-derived glucan. The method has been shown to provide accurate values for samples with cellulose content up to 40 % w/w.3

1.2 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
