  • Permittivity spectroscopy apparatus and method
    Patent number: 5363052
    Abstract: An apparatus and method for measuring the permittivity of a polar solution specimen to enable a determination of the concentration of polar constituents in the specimen. The apparatus (10) employs a band pass filter including containment means (18) formed to contain the polar solution (26) therein and electrically dispose the polar solution (26) as a dielectric element in the band pass filter; conducting means (12); a source of electrical current (56) connected to said band pass filter; frequency variation means (52) electrically connected to the electric voltage source (56) to enable variation of the frequency at which current is applied to the band pass filter; and voltage sensing means (52) electrically connected to sense the peak voltage passed by the band pass filter.
