Turner Designs Hydrocarbon Instruments, Fresno, Calif., has developed a benchtop method to measure oil in water that does not use solvents. Without solvents, the process eliminates the health and safety hazards of transporting, handling and disposing of solvents commonly used in oil-in-water analysis.

The new method also eliminates operator error associated with precision liquid measurements during the analysis process. The benchtop method is compatible with Turner's TD-500D hand-held oil-in-water analyzer. It uses a simple surfactant instead of solvent that gives accuracy and repeatability.
