Abstract

The invention concerns a device for automatically injecting substances solubilised or diluted in a solvent for a gaseous phase chromatographic analysis column (14), wherein it includes a concentration/calcination chamber (10), a vaporization chamber (12) in contact with the chromatographic column (14), a sample support (16) moving in the concentration/calcination chamber between a first position in which the sample is in the concentration/calcination chamber and a second position in which the sample is in the vaporization chamber, as well as a system (18) for scavenging the two chambers with a vector gas.
