Title: Innovations of James L French
Introduction
James L French is an accomplished inventor based in Holland, MI (US). He holds two patents that showcase his innovative contributions to the field of analytical technology. His work primarily focuses on improving processes and materials used in scientific analysis.
Latest Patents
One of his latest patents is for an analytical crucible. This crucible is made of a ceramic material with openings that allow the escape of gaseous byproducts of combustion while securely holding the sample. The preferred embodiment of this crucible is constructed from a porous ceramic material with a mean pore diameter ranging from about 150 to 350 microns. The composition includes at least about 92% alumina and about 7.5% silica, and it is generally cup-shaped.
Another significant patent by James L French is a cleaning system and method for cleaning a flow restrictor in a supercritical fluid extraction system. This system involves coupling a source of oxidizing gas to a flow restrictor during a cleaning cycle. The flow restrictor is heated to a temperature sufficient to oxidize and remove built-up residue from prior analyses. In one embodiment, compressed air is supplied at a pressure of 20 to 40 psi into the flow path for supercritical fluid, while the flow restrictor is heated to a temperature between 300°C and 400°C. This innovative approach allows for effective cleaning overnight when analyses are not typically performed.
