Biobased content quantifying

Method B Accelerator mass spectrometry (AMS) and isotope ratio mass spectrometry (IRMS) techniques to quantify the biobased content of a given product. Sample preparation methods are identical to Method A. Stored CO2 is sent to an AMS facility for final processing and analysis. The maximum error is 1-2% for AMS and 0.1-0.5% for IRMS. [Pg.191]

Method C Liquid scintillation counting (LSC) radiocarbon techniques to quantify the biobased content of a product. Method C uses LSC analysis of sample carbon that has been converted to benzene rather than CO2 solutions of Method A. The maximum error is 3%. [Pg.191]

C-14 signature forms the basis of Standard test method to quantify biobased content (ASTM D6866)... [Pg.576]

C signature forms the basis to identify and quantify biobased content - ASTM D6366... [Pg.285]

Test Method A utilizes Liquid Scintillation Counting (LSC) radiocarbon ( C) techniques by collecting the CO2 in a suitable absorbing solution to quantify the biobased content. The method has an error from 5-10% depending on the LSC equipment used. [Pg.286]
