Title: John E Fulford: Innovator in Mass Analysis Technology
Introduction
John E Fulford is a notable inventor based in Holland Landing, CA. He has made significant contributions to the field of mass analysis technology. His innovative work has led to the development of a unique mass analyzer system that addresses critical challenges in ion signal detection.
Latest Patents
Fulford holds a patent for a "Mass analyzer system with reduced drift." This invention involves a mass analyzer where an ion signal, typically from a plasma, travels through an orifice into a vacuum chamber. The system includes a focusing mechanism that directs the ion signal into a mass spectrometer and ion detector. A key feature of this invention is the incorporation of a small shadow stop placed in the vacuum chamber, which significantly reduces drift in the detected ion signal. This design enhances the accuracy of measurements by minimizing differences in drift for various elements. The focusing system utilizes a Bessel box lens, and further drift reduction is achieved by insulating the stop in the Bessel box lens from the barrel and applying different biasing to the Bessel stop compared to the barrel.
