Man we test everything from Jet Fuel, Gasoline, 6 Oil, Condensate, Benzene, Cumene, Conosol, Coker Gas, Lube Oil, MTBE, etc. i mean there's hundreds of chemicals out there and we pretty much run test on all of them. There are ASTM Standard books on how the methods of each test should be ran and i think there's 9 books all 800 pages long so i'll be here for months telling you what we do...lol But it's a cool job all the left over jet fuel i bring home and use to start fires.
