Help With Obtaining iv Value For Birch Tar Oil

[Dradden]

I am writing  a paper on Russia leather and focusing on the birch tar oil aspect of it that was applied during the currying process. There is some debate about the oxidative stability of the oil and I would like to get the iv value of this oil. As far as I know this is something nobody has yet done. In looking up information on this test and how to do it I keep landing on sites that offer testers but this is far above my budget and can't justify that cost for one test.

 

What I would need if possible is a lab to send it to that could do the test, a one time test kit, or to send somebody a sample who has the equipment to do the test.

 

What would you guys recommend?
