Text of Note

The editor has brought together in a compact and readable form the new methods of analytical chemistry using supercritical fluids. The volume provides comprehensive treatment of supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE); it discusses both theory and practice. The contributions are written by leading experts in their fields with exhaustive practical experience in SFC and SFE. Special attention is given to the description of applications and thus provides the experienced analyst with invaluable information widely scattered in the literature and helps the novice to adopt these new techniques quickly in his laboratory. An addendum includes brand new literature on SFC and SFE.
