Title: Ewald Jöbstl: Innovator in Optical Measurement Systems

Introduction

Ewald Jöbstl is a notable inventor based in Graz, Austria. He has made significant contributions to the field of optical measurement systems, particularly in the determination of transmitted and scattered radiation. With a total of two patents to his name, Jöbstl's work has implications in various scientific and medical applications.

Latest Patents

Jöbstl's latest patents include an optical measurement system designed for the determination of transmitted and scattered radiation in liquid samples. This innovative system features a first detector that captures transmitted radiation, positioned close to or on the axis of the measurement beam. Additionally, a second detector is strategically placed to pick up scattered radiation, located at a distance from the first detector along the capillary axis. The arrangement of these detectors is crucial for accurate measurements, as they lie on different sides of a plane that contains the capillary axis and is perpendicular to the measurement radiation axis.

Another significant patent by Jöbstl is a control or calibration standard intended for use with instruments that measure hemoglobin concentration in blood samples. This standard incorporates scattering particles or beads dispersed in an aqueous electrolyte solution. To ensure stability during storage, the beads are designed with a mean diameter of less than 0.6 micrometers, ideally around 0.3 micrometers, and a volume concentration of less than 1%. The formulation may also include a non-ionic surfactant combined with an antioxidant to prevent long-term agglomeration.
