ABSTRACT:
A method for determining an amount of polar substance in a non-polar media includes adding a surfactant to increase a dispersion of the polar substance in the non-polar media and to increase the optical absorbance of the polar substance in the non-polar media to create a sample, passing an initial optical spectrum through the sample, measuring a resultant optical spectrum exiting the sample, relating the resultant optical spectrum to a predetermined quantitative calibration, and determining a concentration of the polar substance in the non-polar media based on the relation of the resultant optical spectrum to the quantitative calibration.
