    Abstract: A method and apparatus evaluating and improving the properties of fluid formulations is disclosed. The method and apparatus employ impedance spectroscopy (IS) measurements and data analyses to determine IS parameters for fluids representative of fluid formulation. Correlations are determined between the IS parameters and the properties of the fluids, and a modified or new fluid formulation is produced based on these correlations. IS measurements at three or more frequencies are made using probe electrodes in contact with fluids representative of a fluid formulation. The IS data are analyzed uring statistical techniques, equivalent circuit modeling techniques, or a combination thereof. The data analysis provides at least one IS parameter indicative of at least one fluid property for the fluids. At least one correlation is determined between one or more IS parameters and one or more properties of the fluids. A new fluid formulation is developed, responsive to correlations between the IS parameters and the properties of the fluids.

    Abstract: An impedance spectroscopy technique and system for detecting in real time engine coolant contamination in lubricant. A probe is disposed in the lubricant and the probe excited with an a.c. voltage frequency sweep over a selected frequency range. The current and current phase angle are measured at selected frequency intervals and the reactance and resistance computed and plotted at each frequency internal as Nyquist plots. The Nyquist minimum is determined at various lubricant temperatures and a database compiled. The probe is then excited in-situ and current measurements taken for a selected frequency lower than the Nyquist minimum to insure measurement of electrode surfaces characteristics. The reactance and resistance are then computed and the angle Θ of change (slope) of reactance with respect to resistance computed. The value of Θ is then compared with values of contamination concentration ψ versus Θ in a database, and the value of ψ determined by interpolation.
