Method for measuring the concentration and composition of biomass, probe and cell

摘要

Method for measuring concentration and composition of biomass, including the method of measuring electrical impedance within the medium in two regions of said medium, one which is free of cells and one containing cells, with both measurements performed by identical sets of electrodes, to which are connected two frontal stages of the measurement system, thereby obtaining information on the variations of the cell medium conductivity ( sigma e), using this information to correct the estimated culture cell concentration in the cell-containing region. The invention also relates to a probe and a cell.
