Abstract
Method for biomass determination in a medium, in particular a medium containing biological cells suspended in a conductive fluid, the biomass concentration (X) being obtained from a difference between a first capacitance signal (C') of the medium, measured at a first frequency, and a second capacitance signal (C′) of the medium, measured at a second frequency. The method includes a separate correction of each of the measured signals, based at least on one correction level, the first correction level including a correction of the signals measured in accordance with a model dependent on the conductance of the medium at the first and second frequencies. The invention is useful in biomass measurement systems.
