Verfahren und Vorrichtung zur Bestimmung des Volumenanteils von elektrisch isolierenden partikulaeren Stoffen in einer Fluessigkeit

DE 102006009885 A1 UPAB: 20070927 NOVELTY - The method involves forming a suspension (1) by an individual material, in an electrically conducting fluid. The electrical conductivity of the fluid without the individual material and an electrical conductivity of the suspension or a size are measured directly or indirectly during direct current voltage or with an alternating voltage frequency. The conductivity of the suspension represents a measure for the difference between two electrical conductivities. The parts by volume of the individual material are determined on the basis of difference of the two electrical conductivities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for determining the parts by volume in electrically isolated individual material e.g. biological cells, in an electrically conducting fluid. USE - Used for determining the parts by volume of electrically isolating individual materials e.g. biological cells, in an electrically conducting fluid (Claimed). ADVANTAGE - The method involves forming a suspension by an individual material, in an electrically conducting fluid, thus reduces number of electrical connections and technical expenditure as the cells work due to electrically isolated cell membrane
