Title: The Innovative Contributions of Robert B Spokane
Introduction
Robert B Spokane is a notable inventor based in Bellbrook, OH (US). He has made significant contributions to the field of sensor technology, holding a total of 3 patents. His work focuses on enhancing the functionality and accuracy of various sensor systems.
Latest Patents
One of Spokane's latest patents is a sensor capsule designed for CO2 sensors. This innovative sensor capsule facilitates the positioning of an analyte sensitive element, such as a CO sensor, at the end of a fiber optic probe. The design includes a dye layer defined by a dye well, a fluorescent dye solution, and apertures formed in a silicone sensor membrane. A TEFLON® covering membrane is strategically placed over the silicone membrane to retain the dye layer within the well. Additionally, a perforated metal disc is positioned beneath the silicone membrane to provide support and resist swelling of the dye layer. This sandwich sensor structure is housed within an outer casing, with an insert member that snap fits into the outer housing, allowing for easy replacement in association with a probe tip used for forming the fiber optic CO sensor.
Another significant patent involves methods for reducing the level of interferants in biosensor systems. Spokane's improved methods and compositions inhibit interference from formaldehyde in polarographic analytic methods. In the enzymatic oxidation of methanol to hydrogen peroxide and formaldehyde, formaldehyde acts as an interfering agent. To mitigate this interference, an amine-containing formaldehyde scavenger is introduced into the test system. This scavenger, preferably a polyalkyleneimine such as polyethyleneimine, has a molecular weight ranging from about 200 to 1,000,000 amu. This invention is particularly beneficial for polarographic analytical apparatus that utilize laminated membrane type enzyme electrodes for amperometric measurement.
