Title: Michel Marc Levart: Innovator in Colloidal Measurement Technologies
Introduction
Michel Marc Levart is a notable inventor based in Issy-les-Moulineaux, France. He has made significant contributions to the field of colloidal science, particularly in the measurement of colloidal particle mobility in electrical fields. With a total of 2 patents to his name, Levart's work has implications for various applications in environmental science and engineering.
Latest Patents
Levart's latest patents include a method for measuring the mobility of colloids in an electrical field. This invention relates to a method for measuring the movement of colloidal particles in suspensions or solutions. The apparatus used in this method comprises an electrophoresis tank equipped with two electrodes, between which an electrical field can be applied. A beam of radiation produced outside the tank, having a thickness of not more than 1000 micrometers, is directed to skim the electrode from which the particles move under the effect of the electrical field. The optical density of the liquid is measured first without applying the electrical field and then again after applying the field for no more than 10 seconds.
Another patent focuses on an improved method and apparatus for measuring the movement of colloidal particles in suspensions or solutions. This invention also utilizes an electrophoresis tank equipped with two electrodes and a filtering membrane positioned substantially parallel and equidistant to the electrodes. A flat beam of radiation is directed to skim the side of the membrane from which the particles move under the effect of the electric field. This improved arrangement helps eliminate the influence of secondary interfering phenomena, particularly when measuring the movement of colloidal particles in highly mineralized waste waters.
