Title: Mark Julian Stockdale: Innovator in Gaseous Detection Technologies

Introduction

Mark Julian Stockdale is a notable inventor based in Harston, GB. He has made significant contributions to the field of gaseous detection technologies, holding a total of 3 patents. His innovative work focuses on developing advanced detection systems that enhance the ability to identify gaseous analytes in various environments.

Latest Patents

One of Stockdale's latest patents is the "Water Immersible Detector." This apparatus is designed to detect the presence of gaseous analytes in water. It features a submersible housing that encloses a waterproof sensing chamber. The chamber includes a first wall made of a material transparent to UV light and a second wall formed by a gas-permeable membrane. This design allows gas dissolved in water to enter the sensing chamber during operation. The device also incorporates spaced sensing electrodes and a circuit that measures the current flowing through these electrodes due to the ionization of gas by UV light. Additionally, a third electrode is positioned in the chamber, with a circuit that applies a voltage to reduce condensation by hydrolyzing any droplets in contact with the electrodes.

Another significant invention is the "Electrode Contact Pellet and Associated Photoionisation Detector Assembly." This demountable pellet serves as an electrode contact assembly. It consists of a base with multiple electrodes arranged in spaced parallel planes, each having respective contacts protruding from them. The closure for the base engages at least one of the electrode contacts. In its unassembled condition, the contacts lie in parallel planes, while in the assembled condition, at least one contact shifts to a different plane.
