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.
