ABSTRACT:
A method of measuring relatively small amounts of saturated hydrocarbon oil in an essentially nonconductive liquid, comprises the steps of mixing the oil and liquid with a conductivity additive such as colloidal metal-containing particles to render the oil conductive without rendering the nonconductive liquid conductive and then measuring an electric current passed through the mixture to obtain an indication of the amount of oil in the mixture. The metal-containing particles may for example be selected from the group consisting of chromium dicarbide, chromium silicide and silver peroxide.
