METHODS FOR MEASURING RENEWABLE BIO-SOURCE CONTENT IN RENEWABLE BIOPLASTIC MATERIALS

摘要

The present invention relates to improved methods for measuring the renewable bio-source carbon content and renewable bio-content in renewable bioplastic resins produced in manufacturing plants. In particular, the present invention relates to measuring the renewable bio-source carbon content in renewable bioplastic resins produced during a production run by correlating measured d13C values are measured by iTOC-CRDS and CM-CRDS with actual renewable bio-source carbon content measurements (AMS or LSC 14C) via a linear regression.
