Title: The Innovative Contributions of William R. Davidson
Introduction
William R. Davidson is a notable inventor based in Thornhill, CA. He has made significant contributions to the field of science and technology, holding a total of 3 patents. His work primarily focuses on advanced methods for analyzing substances and improving detection techniques.
Latest Patents
One of his latest patents is titled "Frontal affinity chromatography/MALDI tandem mass spectrometry." This invention utilizes sol-gel derived monolithic silica columns containing entrapped dihydrofolate reductase for frontal affinity chromatography of small molecule mixtures. The output from the column is combined with a second stream containing the matrix molecule (HCCA) and is directly deposited onto a conventional MALDI plate. This process is controlled by a computer-operated x-y stage, creating a semi-permanent record of the FAC run. The use of MALDI MS allows for a decoupling of the FAC and MS methods, enabling the use of significantly higher ionic strength buffers for FAC studies, which enhances the retention of protein activity over multiple runs.
Another significant patent is the "Method and apparatus for detecting a contraband substance." This method involves agitating freight cargo containers to disturb particulates within. Air containing these particulates is sampled, and the particulates are collected. The collected particulates include naturally occurring particulates that have absorbed vapors of the contraband substance while the container was closed, as well as particulates of the contraband substance itself. These particulates are then heated to a temperature above 160 degrees Celsius to drive off vapors indicative of the contraband substance, which are subsequently analyzed in a mass analyzer.
