As I previously shared, the result for vandium in the low-sulfer diesel (#2 fuel oil) came back at <0.1 ppm versus the "spec" of <0.05 ppm.  I just talked to the lab supervisor at Saybolt whom performed the analysis; and according to him there is no practical way of measuring the vanadium content more precisely than within one-tenth of a ppm.  

The only way he knows of is to use a NMR (nuclear magnetic resonance) machine that NASA uses to analyze rocket fuel.  He is not sure whether or not the government would allow use of such a machine but estimates that, if they did allow, it could cost upwards of $10,000. 

Please let me know if we should pursue this matter any further.


Thanks,

Charlie
