Title: Innovations by Inventor Nicholas J Barker
Introduction
Nicholas J Barker is an accomplished inventor based in Mariposa Township, California. He holds a total of 3 patents that showcase his contributions to the field of detection technology. His work primarily focuses on developing advanced systems for identifying chemical compounds and contaminants.
Latest Patents
One of his notable inventions is a photoionization detector with multiple ionization cells. This device is designed to detect the presence of chemical compounds in various fluid samples. It utilizes a single source of ultraviolet (UV) radiation to emit high-energy photons into at least two ionization cells. Each cell is equipped with fluid inlets and outlets, allowing independent samples to be introduced and exposed to UV radiation. This innovative design ensures that any molecules with an ionization energy lower than the energy of the photons are ionized, generating an electrical current.
Another significant patent is a system for detecting noxious contaminants in beverages and potable liquids. This device is particularly useful in high-speed bottle lines, where it detects contaminants in returned bottles. The sample chamber rotates on a carousel unit, allowing for efficient sampling. A blast of air forces the contents of the bottle through an aperture into the sample chamber. The analyzer, which includes a UV absorption analyzer and a photoionization detector, is controlled by a computer that issues reject instructions if contaminant levels exceed a predetermined threshold.
