The review deals with large-volume injection techniques in capillary GC employing classic split/splitless and programmable-temperature vapourisation chambers. The basic principles, advantages and limitations of large-volume injection using a programmable temperature vapouriser operating in the solvent vent mode, splitless large-volume injection with vapour overflow and a hot vapourisation chamber-precolumn-solvent vapour exit system are described. An overview of applications is given.
