Title: The Innovative Mind of Graham Anthony Fuggle

Introduction: Graham Anthony Fuggle, an accomplished inventor based in North Harrow, GB, has made significant contributions to the fields of ion measurement and electronic sampling. With two patents to his name, Fuggle's innovations have paved the way for advancements in detecting ion concentration and pH levels in solutions, as well as in photographic chemical analysis.

Latest Patents: Fuggle's recent inventions include a sophisticated apparatus and method for simultaneously measuring the concentration of a selected ion species in a solution and the pH of that solution. This patented system employs an ion selective electrode, a reference electrode, and an ISFET immersed within the solution. The ion concentration is derived from the potential difference between the ion selective electrode and the reference electrode, while the pH is determined using a separate circuit that monitors the current flowing between the ISFET and the reference electrode. Notably, the design ensures isolation between the two circuits through the use of a high resistance and a virtual earth connection, enhancing the accuracy and reliability of the measurements.

The second patent involves an electronic sampling circuit designed for determining redox potentials and corresponding species concentrations in photographic solutions. This innovative circuitry applies a linear ramp of square wave voltage to a first electrode immersed in the solution. Current drawn by an adjacent electrode is converted to a voltage for sampling purposes. Additionally, sample-and-hold circuits store signals at critical points in the square wave pulse, allowing for precise calculations of differences between analogue signals with minimal amplitude discrepancies, all facilitated by a cost-effective analogue-to-digital converter.
