Introducing Fogale Systems

The technique is based on the findings of pioneers researchers such as Fricke (1936), Schwan (1950), and Hanai (1960), who demonstrated the relationship between the biomass volume fraction and the variation of the medium dielectric permittivity, in the beta dispersion frequency range.

Under the influence of an electric field between two electrodes, cells with intact plasma membranes are polarized and behave as tiny capacitors. the resulting capacitance is measured between a second pair of electrode pair an can be accurately correlated to the biomass concentration. Unlike conventional optical instruments, the system only responds to living cells ans is not sensitive to gas bubbles, microcarriers, cell debris and other particles in suspension.
