Introduction

Ernest Bryant Mansfield is a notable inventor based in Pittsburgh, PA. He is recognized for his significant contributions to the field of sulfur analysis. His innovative methods have paved the way for advancements in chemical analysis and environmental monitoring.

Latest Patents

Mansfield holds a patent for a "Method and apparatus for sulfur analysis." This invention involves a system for determining the sulfur content of a sample by combusting it to form a gas. In this process, sulfur is primarily converted to sulfur dioxide in a known ratio with sulfur trioxide. The gas sample is then passed into a reaction vessel containing a pyridine solvent, where the sulfur dioxide is scrubbed from the sample through a binding action with the pyridine. The bound sulfur dioxide is titrated with elemental iodine in the presence of alcohol and excess water. This method allows for simultaneous and continuous trapping and titration, utilizing a polarized electrode pair for detection. The end point is determined when the electrodes become current conducting in the presence of excess iodine, allowing for accurate sulfur analysis.
