PROCEDE ET SYSTEME POUR COMPTER EN LIGNE ET IN SITU DES CELLULES DANS UN MILIEU DE CULTURE BIOLOGIQUE

摘要

An on-line and in situ cell counting in biological culture medium comprises measuring of capacitance of medium or measuring conductance of medium, at distinct frequencies varying within predetermined range of measurement frequencies; extracting information on variation of permittivity due to beta -dispersion in medium, from capacitance measurements; and processing of information on variation of permittivity in order to provide information regarding counting of cells in medium.
