In 1964, University of Utah chemistry professor J. Calvin Giddings enunciated a theoretical platform, “unified separation science,” that could confer the resolving power of GC to LC. Giddings’ model combined the higher mobile phase diffusion and efficiency of GC with LC’s higher selectivity via orthogonal separation modes. His vision has been made a reality through supercritical fluid chromatography (SFC), which uses supercritical or subcritical carbon dioxide as the mobile phase.

The University of Washington research vessel Thomas G. Thompson is loading up for six weeks at sea. When the team returns to Seattle in late August they will have extended the cabling to key research sites, an important part of building the first real-time, continuous eye on the mysterious creatures, currents and geologic forms in waters off the Pacific Northwest coast.
