  • Analytical or monitoring apparatus and method
    Patent number: 5569591
    Abstract: Cellular biological material (such as living tissue) is analysed or monitored by applying an AC electrical potential across the biological material so as to produce a nonlinear dielectric spectrum, and obtaining a detectable signal corresponding to the resulting spectrum. The potential is of a first frequency and the measured response at one or more second frequency substantially not overlapping with the first frequency.
    Type: Grant
    Filed: July 21, 1994
    Date of Patent: October 29, 1996
    Assignee: University College of Wales Aberystwyth
    Inventors: Douglas B. Kell, Andrew M. Woodward
  • Determination of biomass
    Patent number: 4965206
    Abstract: Method and apparatus for the determination of biomass in a suspension, such as a culture, in `real` time and a fermentation process using the method. In the method the electrical capacitance of the suspension is measured and from the measurement the volume fraction of the suspension enclosed by the cytoplasmic membranes of the cells (biovolume) is determined.
    Type: Grant
    Filed: February 9, 1990
    Date of Patent: October 23, 1990
    Inventor: Douglas B. Kell
  • Determination of biomass
    Patent number: 4810650
    Abstract: Apparatus for the determination of biomass in a suspension and its use in a fermentation apparatus. The apparatus includes electrodes to be placed in the suspension and the following other components: circuit for applying an alternating voltage between the electrodes; circuit for providing a current signal indicative of the current in the current electrode circuit; circuit for providing a voltage signal indicative of the voltage between the ratio between the value of the voltage signal and the value of a quadrature component of the current signal, or vice versa, to provide a capacitance dependent signal.
    Type: Grant
    Filed: September 22, 1987
    Date of Patent: March 7, 1989
