摘要： A system and method for monitoring and controlling the properties of fluids is disclosed. The inventive concept employs impedance spectroscopy (IS) measurements, and is suitable for real-time, in situ, monitoring and quality control operations, such as quality control during the manufacture of blended lubricants. IS data are obtained for three or more frequencies, where the lowest frequency is less than 1 Hz and the highest frequency is greater than 1 Hz. These data may be interpreted according to statistical techniques such as Principal Component Regression, analytical techniques such as equivalent circuit modeling, or by a combination thereof. The data analysis provides characteristics, or IS signatures, relating to the properties of the fluid. IS signatures for a test fluid are compared to IS signatures for calibration fluids to determine whether the properties of the test fluid fall within specified limits. Quality control adjustments to the test fluid properties may be performed based on the IS signatures.

摘要： A method and apparatus for evaluating and improving the properties of fluid formulations is disclosed. The inventive concept employs impedance spectroscopy (IS) measurements and data analyses to determine IS parameters of fluids representative of a fluid formulation. Correlations are determined between the IS parameters and the properties of the fluids, and a modified or new fluid formulation may be developed responsive to the correlations.
