Title: David S Jones: Innovator in Mass Spectrometry

Introduction

David S Jones is a notable inventor based in Sale, GB, recognized for his contributions to the field of mass spectrometry. With a total of three patents to his name, he has made significant advancements in the analysis of samples using super-critical fluids.

Latest Patents

One of his latest inventions is the "Super-critical fluid mass spectrometer." This invention provides a mass spectrometer designed for the analysis of a sample dissolved in a super-critical fluid. The fluid is expanded directly into an ionization chamber without undergoing a liquid-gas transition, and the sample is ionized through a glow discharge established in the chamber. The electrodes used for the discharge are integrated into the wall of the ionization chamber and the tube through which the super-critical fluid enters. This spectrometer is primarily intended for use with a super-critical fluid chromatograph.

Another significant patent is the "Solution analyzing mass spectrometer." This mass spectrometer is suitable for analyzing the eluent of a liquid or supercritical fluid chromatograph. To maximize the flow rate of fluid entering its ionization chamber, aperture closing means are provided between an electron or particle source and the entrance aperture into the ionization chamber. These means can close the aperture when ionization is not required, thereby increasing the maximum flow rate into the chamber. Sample ionization can be achieved through a glow discharge or a liquid ionization process such as thermospray ionization.
