Every link I could pull up says that all tanks are filled from the same base supply.
Impurity
possibly could come from the handling and care of the tanks used
Why would you think that pilots deserved or required purer oxygen than people who depend on it for survival ?
"All oxygen supplies come from a very small number of vendors and is normally delivered in 25,000 gallon refrigerated tanks.
The manufacturing process is so thorough and clean that the finished product meets all usage specifications right from the tank. However, just to be sure, any lot of oxygen destined to be medical oxygen is batch tested for aromatics (oils, Benzene, and other impurities that appear in the manufacturing equipment). ABO (aviation breathing oxygen) is also tested for moisture content, while welding oxygen comes straight from the vendor with no additional additives or testing.(snip)..........
Although hundreds of FBOs around the country have aviation oxygen available, industrial oxygen (
remember, it’s all the same) can also be used for Part 91 operations.
