View Full Version : Petroleum hydrocarbon in water

01-03-2013, 03:15 AM
I am trying to develop method for petroleum hydrocarbon in water. A typical sample I would get would have the fractions found in motor oil, including BTEX. I would like to prepare a spiked sample in the lab and analyse it for validation with GC-MS and GC-FID. I am having trouble with preparing it. If I mix few drops of motor oil in water and shake it, I can not get an emulsion. Same if I add a little bit of methanol or acetone.

Is there a better way of preparing a spiked sample of HC in water? Any help appreciated.
