Lubricity of diesel

SkyPup · Dec 7, 2005

There are only a total of 7,000 oil wells that have ever been drilled in the entire Middle East (although many counties in Texas have that many wells themselves). You could easily trace that oil all the way back directly to where it was pumped out of the ground anywhere in the world.

( Thanks Sky Pup. I was calling the lawyer to get the expert we used phone # but you did an admirable job answering the question. /forums/images/graemlins/wink.gif )

No, please go ahead and give me the number.

( 10 microliters of suspect contaminated diesel fuel injected into a Hewlett-Packard gas chromatograph onto a polymeric hydrophobic reverse phase column matrix with a flame ionization detector will give an exact identificaiton of the diesel fuel that will stand up in court the same as a fingerprint or a DNA sample in less than twenty minutes. )

And if I give you a sample that is a 50/50 mix of Phillips and Mobil diesel fuel, what result do you get?

A 50:50 mixture of Phillips and Mobil.

Really.

I've got my sample, that I'm going to guess consists of twenty to thirty suppliers all blended together. Where do I send it? I want to see this.

Getting a bit rediculous dont you think? /forums/images/graemlins/grin.gif

Bet you dont believe in DNA testing either do you?

This is possible, the lab the floor up does this all day long for biochemistry, by top cutting edge scientist. Perkins-Elmer trial runs many a new prototype spectoscope in that lab. Extremely expensive equipment. One of the scientist I talk with is very much in to biodiesel fuels, as a hobby subject. Seperating 30 blended diesel fuels with their own unique signature would just take time. It's all doable. It's when you go to telling from which dino it came from, then that shows you real expertist!!! /forums/images/graemlins/grin.gif Thanks Skypup! Always a pleasure reading you posts! /forums/images/graemlins/smile.gif

Yes -> REALLY 

What did you expect??? /forums/images/graemlins/laugh.gif

Sounds great, do you want the results in nanograms, picograms, or femtograms? /forums/images/graemlins/cool.gif

HGM, I don't think it's ridiculous. My science stops at Interaction of Elements and High School chemistry but I think I understand this much:
You need to have unique trace elements that signature you to every single source. If that is the case, then you can identify all 30 sources with certainty and should even be able to nail the mix percentages. Lacking that, it's a number crunch of the results and maybe you get real close, but no guarantee you nailed both sources and percentages without a unique signature element. Now Skypup may further educate us on this and my science is 30 years old, but that's my understanding. Not as technical as we think IMO, at this level anyhow.
