Abstract:
A sensitive arrangement for determining presence of oil, at low parts per million, in water. It employs infrared absorbtion measurement, and first mixes the water with an oil solvent that may be separated from the water after taking any oil into solution. Also, the solvent is one which does not have any significant infrared absorbency at a predetermined wave length, which does have absorbency by hydrocarbons. After separation of the oil solvent, it is continuously passed through an absorption cell in an infrared spectrometer, to monitor the presence of oil in the water.
