Tracking Biogenic Carbon in Liquid Fuel Blends using Conventional Mass Spectrometry and Infrared Spectroscopy

Scott Herndon, David Nelson

Aerodyne Research, United States of America

This work demonstrates the analytical basis for an IR laser measurement system with the potential to perform routine quantification of biogenic carbon content in liquid fuel products at working refineries. The IR system results for 13CO2/12CO2 compare favorably with gold-standard isotope ratio mass spectrometry (IRMS). The IR system employed a predilution stage that emploted transfer techniques to suppress fractionation.

We will present the performance potential for routine quantification for mixtures of C–3 and C–4 biogenic carbon sources mixed with fossil feedstock.

Finally, we will show how the IR based apparatus can directly quantify stable isotopologs that are isobaric in IRMS instruments.
