Title: Hervé Cottet: Innovator in Particle Size Distribution Analysis

Introduction

Hervé Cottet is a notable inventor based in Le Cres, France. He has made significant contributions to the field of particle size distribution analysis, holding three patents that showcase his innovative methods. His work is particularly relevant in scientific research and applications involving mixtures of particles and molecules.

Latest Patents

Cottet's latest patents include a method for determining the size distribution of a mixture of particles using Taylor dispersion. This method involves injecting a sample into a capillary with an eluent flowing through it. The sample is transported along the capillary, generating a measurable Taylor dispersion phenomenon. A suitable sensor in the detection section generates a signal characteristic of this dispersion, which is then processed to obtain an experimental Taylor signal. The analysis of this signal allows for the breakdown into a sum of Gaussian functions, providing insights into the size distribution of the mixture.

Another significant patent focuses on the determination of the hydrodynamic radii of constituents in an admixture through capillary electrophoresis. This method involves separating the constituents within a capillary and inducing a pressure difference to cause migration towards a detection device. By analyzing the Taylor dispersion produced, the hydrodynamic radius for each constituent can be determined based on the detection time of a marker and the elution profile of the constituents.
