Method for investigating the condition of a bacterial suspension through frequency profile of electrical admittance










Image Number 9 for United States Patent #4810963.

A method of investigating the condition of biological particles, in particular the fraction of viable cells in a bacteria population involves applying a voltage and monitoring the voltage induced by magnetic induction in a detector coil. The applied voltage is of a variable frequency alternating voltage and is preferably induced in the medium through a drive coil.
