Case Studies
Real industrial applications of spectroscopy intelligence — from field trials to live operational deployments.
FAME Concentration in Biodiesel Quantification
Fatty Acid Methyl Ester (FAME) concentration must be tightly controlled across the biodiesel supply chain — from blending to regulatory compliance to jet fuel contamination risk. Traditional lab-based testing creates costly delays at every stage.
Challenge
- Time-consuming lab verification slows supply chain decisions
- FAME limit enforcement required in diesel blends (<7% in Singapore and EU)
- High CPO demand creates pressure for rapid concentration checks
- Jet fuel adulteration with FAME is a serious aviation safety risk
Spectroscopy Approach
- Portable NIR/MIR spectroscopy for on-site FAME quantification
- Replaces lab-based testing with immediate field measurements
- Applicable at blending plants, import terminals, pump stations
- Covers full range from pure biodiesel to trace contamination
Validation
- Validated against international standard ASTM D7371
- Excellent model accuracy: R² = 0.999
- Tested across a wide range of FAME concentrations and fuel matrices
Outcome
- On-site regulatory compliance verification in seconds
- Enforcement tool for fuel quality authorities
- Prevents costly batch rejections and supply chain delays
- Protects aviation safety by detecting FAME contamination in jet fuel
Validated to ASTM D7371 — R² = 0.999 across the full FAME concentration range. Directly replaces lab-based testing at a fraction of the cost and time.
