Title: Yvonne M Walbroehl: Innovator in Fluid Stream Measurement

Introduction

Yvonne M Walbroehl is a notable inventor based in Midland, MI (US). She has made significant contributions to the field of fluid measurement technology. Her innovative work has led to the development of a unique apparatus that enhances the monitoring of analyte concentrations in fluid streams.

Latest Patents

Yvonne holds a patent for a "Capillary fluid stream concentration measuring apparatus and method." This invention provides an apparatus for monitoring the relative concentration of an analyte in a fluid stream. The apparatus includes a capillary tube that contains the flowing fluid, along with optics that direct a single beam of monochromatic light through the tube. This setup produces a diffraction pattern with several interference fringes. A translatable photodiode monitors a portion of one of the fringes passing through a light-limiting slit. This process generates a signal proportional to the concentration of the analyte based on the varying intensity of the monitored fringe. The capillary tube is preferably made of fused silica and has an inner flow diameter of 100 micrometers or less.
