ASTM D7371: A New Path to FAME Analysis in Diesel
Main Author
Daniel Vetter - Anton Paar
Abstract:
As biodiesel blending becomes increasingly common, accurately determining FAME (Fatty Acid Methyl Ester) content in diesel fuel is essential for quality control and regulatory compliance. ASTM D7371 offers a faster, simpler alternative to traditional gas chromatography methods, using mid-infrared (FTIR) spectroscopy to determine FAME content directly.
Attendees will learn the operating principles behind FTIR-based FAME analysis, how D7371 compares to GC-based methods in terms of speed and complexity, and best practices for calibration, method validation, and sample handling. The session will also address common analytical challenges and how automated FTIR systems support consistent, reliable results across varying blend levels.
