Title: Innovations by Robert C Prescott
Introduction
Robert C Prescott is a notable inventor based in Foxborough, MA (US). He has made significant contributions to the field of chromatographic technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and accuracy of chromatographic processes.
Latest Patents
One of Prescott's latest patents is a temperature control system for chromatographic apparatus. This invention includes a process chromatograph that separates fluid samples into their individual components. It features a density-responsive detector connected to the column output, producing a pressure signal that represents the concentration of the separated components. The system is designed with a thermally-insulated housing, where the interior is heated and maintained at a set-point temperature by a temperature regulating system. Heat energy is supplied by steam to one section of a two-section tubular heat-exchanger, while a stream of air flows through the other section to transfer heat into the housing interior. The rate of heat transfer is automatically controlled by a thermostatic control that continuously adjusts the air flow to maintain the desired temperature.
Another significant invention by Prescott is the pneumatic chromatograph. This all-pneumatic process chromatograph features a pneumatically-actuated sample-injection valve and an orifice connected in the column output line to develop a pressure signal corresponding to fluid density. It includes a pneumatic amplifier for strengthening the pressure signal and pneumatically-operated control means for developing a periodic sample-valve actuating signal. The pneumatic control means can automatically adjust the time of peak selection in response to changes in actual peak elution time. The temperature-sensitive elements of this apparatus are contained in a chamber heated by steam, with the rate of heat transfer regulated pneumatically to maintain a relatively constant temperature.
