Title: Innovations of Charles J Oberhauser
Introduction
Charles J Oberhauser is a notable inventor based in Belmont, MA, who has made significant contributions to the field of chromatography. With a total of three patents to his name, he has developed innovative methods and apparatus that enhance the performance of liquid chromatography systems.
Latest Patents
Oberhauser's latest patents include a method for monitoring high-performance liquid chromatography. This method involves monitoring the performance of liquid chromatography apparatus, which includes an elongated chromatography column. The apparatus features a conduit coupled to the column inlet for introducing a flow of liquid into the column at very high pressure. Variations in a selected electromagnetic property, such as electrical conductivity, of the liquid flow are measured in the conduit. The apparatus is designed to allow for the sequential or simultaneous introduction of sample liquid and eluant with minimal band-spreading.
Another significant patent is for a high-performance liquid chromatography method and apparatus. This invention involves a high-pressure liquid chromatographic apparatus where a fluid mixture containing at least one solute is loaded into the column. A number of plugs of different eluant fluids are injected into the column in a manner that minimizes the amount of eluant required. The injections are designed to ensure that the flow of eluant fluids through the column occurs at speeds sufficient to induce turbulent flow, thereby reducing the time required for the mixture and eluant fluids to traverse the column.
