Raman Analyzers for Biofuels & Renewal Fuels
Biodiesel, also known as fatty acid methyl ester (FAME), is a renewable diesel fuel increasingly blended with conventional fuels like jet fuel to reduce carbon emissions and promote sustainability. The ability to accurately detect and quantify trace concentrations of FAME in jet fuel is critical for ensuring compliance with fuel specifications and maintaining optimal performance in aviation applications.

Spectral Identification of FAME in Jet Fuel
Raman spectroscopy excels at detecting biodiesel in jet fuel blends. Two dominant FAME peaks at 1660 cm⁻¹ (C=C) and 1750 cm⁻¹ (C=O) stand out clearly in the Raman spectrum, even at low concentrations. These peaks provide a reliable basis for quantifying the biodiesel content in jet fuel blends.
In a comparative analysis, spectra from pure jet fuel and jet fuel containing 5% biodiesel (FAME) demonstrate the strong Raman response of biodiesel, with an intensity-scaled biodiesel spectrum included for reference. The spectral clarity and resolution of these peaks enable precise differentiation and quantification of FAME in jet fuel.
High-Precision Measurements
Raman predictions of biodiesel concentrations in jet fuel, based on the 1660 cm⁻¹ (C=C) peak, achieve exceptional accuracy. The standard deviation of the difference between actual and predicted concentrations is just 0.08 vol%, ensuring precise and reliable measurements. Lower detection limits, down to the 1000 ppm range, can be achieved by employing a high-performance CCD detector, increasing laser power, or extending the sample integration time.
HORIBA PI-200 Raman Technology Advantage
The study utilized HORIBA’s standard PI-200-L spectrograph to measure trace concentrations of FAME in jet fuel with remarkable accuracy. Background-corrected spectral responses revealed the sensitivity and robustness of Raman technology in distinguishing even minute concentrations of biodiesel in complex fuel matrices.
Applications for Refiners and Fuel Producers
- Real-Time Monitoring: Ensure precise control of FAME concentrations during blending processes.
- Regulatory Compliance: Meet stringent aviation fuel standards that dictate allowable biodiesel content.
- Enhanced Efficiency: Avoid overuse of additives and blending stocks, optimizing production costs
