    摘要: Described herein are devices, systems, and methods for determining the composition of fluids, and particularly for describing the identity and concentration of one or more components of a medical fluid such as intravenous fluid. These devices, systems and methods take multiple complex admittance measurements from a fluid sample in order to identify the identity and the concentration of components of the fluid. The identity and concentration of all of the components of the solution may be simultaneously and rapidly determined. In some variations, additional measurement or sensing modalities may be used in addition to admittance spectroscopy, including optical, thermal, chemical, etc.

    摘要: 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.

    摘要: Impedance spectroscopy is used to determine values associated with properties of a substance such as a fluid. In some embodiments, the present invention is applied to engine lubricants. A spectral matrix is constructed that comprises data taken from spectral plots. Also constructed is a result matrix comprising known quantities of a plurality of fluid constituents. A known analytic technique is performed on the spectral matrix to identify at least one principal component having significant influence on the spectral matrix. A reduced spectral matrix, wherein each column in the reduced spectral matrix is associated with a principal component having significant influence on the spectral matrix, is next created. A statistical technique uses the reduced spectral matrix and the result matrix to create at least one prediction equation. The prediction equation is used to predict at least one property in a second substance in situ.
