The reaction product development is compared to a known standard to determine the presence or amount of the non-triglycerides in the oil.Field of SearchLUBRICANT, GREASE, MINERAL OIL, HYDROCARBON OIL PRODUCT, OR FATS OR LIPIDS FOR OXIDATION (E.G., BREAKDOWN PRODUCTS OR CONTAMINATION, ETC.)Acidity, basicity or neutralization number OPTICAL RESULT Including use of a solid sorbent, semipermeable membrane, or liquid extraction FOOD OR DAIRY PRODUCTS Test package or kit Including titrator OIL TESTING (E.G., CONTAMINATION) WITH SAMPLE PREPARATION |
