• Sharing distribution systems with jet fuel
• Surface-active biodiesel sticking to surface
• Cross-contamination in jet fuel
• Stability and freezing point of jet fuel
• Engine problems or potential flame outs

GC/MS
HPLC
FT-IR
• Extensive technical training
• Large and expensive
• Off-site; lack of immediate
results
• Costly: $50k-100k
• Large and heavy: 20 kg weight
• Not sensitive: Biodiesel >20 ppm
