Title (EN) INVESTIGATION OF CONDITION OF BIOLOGICAL PARTICLES
(FR) PROCEDE D'INVESTIGATION DES CONDITIONS DE PARTICULES BIOLOGIQUES
Abstract:
(EN) 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.
(FR) Procédé d'investigation des conditions de particules biologiques, notamment de la fraction de cellules viables dans une population de bactéries, consistant à appliquer une tension et à contrôler la tension induite par induction magnétique dans une bobine détectrice. La tension appliquée est une tension alternative de fréquence variable et est induite de préférence dans le milieu par l'intermédiaire d'une bobine d'excitation.
