  • Patent number: 5055410
    Abstract: A method and diagnostic test unit for the determination of one or more non-triglycerides in an oil using an oil-miscible test solution prepared from an oil-miscible vehicle of monoglycerides, diglycerides or mixtures thereof and an indicator deliverable in admixture with the vehicle for assaying the non-triglycerides, wherein the indicator in combination with the non-triglycerides forms a reaction product characteristic of the amount of the non-triglycerides, and the indicator and vehicle are present in quantities and at a pH effective to provide detectable quantities of reaction product. The reaction product development is compared to a known standard to determine the presence or amount of the non-triglycerides in the oil.
