With a total of 2 patents, Himes has established himself as a key figure in the development of advanced chromatographic technologies.

Latest Patents

One of Himes' latest patents is an on-line multidimensional chromatographic system with large volume. This system couples a liquid chromatograph to a supercritical fluid chromatograph. It includes an inlet column for depositing a fraction of interest eluting from the liquid chromatograph. An interface is interposed between the inlet column and the supercritical fluid chromatograph for receiving and trapping an analyte from the deposited fraction on an impactor surface. A valve arrangement controls fluid flow throughout the system. After the fraction of interest has been deposited in the inlet column, the liquid chromatograph solvent is removed. The deposited fraction is then extracted from the inlet column in a supercritical fluid stream. The supercritical fluid stream is directed into the interface, where the analyte is trapped while the supercritical fluid is decompressed and vented. A subsequent supercritical fluid stream is then used to introduce the trapped analyte directly into the analytical column of the supercritical fluid chromatograph. This innovative system can also introduce samples contained in large volumes of solvent without prior liquid chromatographic separation.
