✦ Synopsis

Concurrent solvent evaporation is suited for coupled HPLC-HRGC if solutes elute at intermediate to high column temperatures-otherwise retention gap techniques are more appropriate. Concurrent eluent evaporation using a loop-type interface requires that the GC oven temperature during eluent introduction be above the eluent boiling point at the carrier gas inlet pressure applied. An experimental background is given for facilitating selection of the appropriate column temperature.

Dedicated to Marcel Golay, the inventor of capillary gas chromatography, on the occasion of his 85th birthday.
