Chromes: Webster's Quotations, Facts and Phrases
Nonfiction Usage Patent UsageChromatography system: Patented by Eldred H. Chimowitz and Frank VanPuyvelde on May 3, 1992. Abstract: A system (method and apparatus) for optimizing the relationship between resolution and time in chromatograms, especially chromatograms obtained by supercritical fluids (CSF) chromatography. The pressure or temperature or fluid density of the solution caring the material under analysis is varied dynamically under computer control to provide an optimum capacity factor for a particular transporting fluid in a particular chromatographic system to obtain the resolution of interest in the shortest period of time.METHOD FOR ANALYZING CHROMATOGRAMS: Patented by Paul B. Crilly on September 1, 1987. Abstract: A method for resolving severely overlapped chromatogram peaks using Jansson's iterative deconvolution method is disclosed. The method requires only a knowledge of the impulse response function of the chromatographic apparatus and maximum peak height. A high degree of resolution is achieved without significantly degrading the chromatogram signal to noise ratio.Method for comparison of similar samples in liquid chromatography/mass spectrometry: Patented by Willem Windig and William F. Smith on July 8, 1999. Abstract: A method is disclosed to reduce the time needed to analyze data generated from very similar samples, emphasizing the differences obtained, from the combined technique of liquid chromatography/mass spectrometry, a technique used to analyze the composition of materials. The method quickly compares each mass chromatogram between similar samples and displays the limited number of mass chromatograms that are different to the analyst.PROCESS FOR THE VISUALIZATION OF SUBSTANCE STAINS ON LAYER CHROMATOGRAMS: Patented by Walter Muller on June 1, 1991. Abstract: The present invention relates to a process for the visualization of substance stains on dry layer chromatograms without further addition of a mobile phase, which device has foil of at least one layer and comprises one or more reagents for the visualization of substance stains.Bibliographic UsageAbelson, D.
