For oil & grease test under APHA 2540B standard, there are few type of solvent found in Standard Method 21st edition, which are n-hexane, isomer C6, Acetone, Hexadecane & Stearic Acid. However the percentage are not clearly stated.
I would like to identified the best solvent to use for oil & grease test. Is anybody have the idea?
Thank you.
