ABSTRACT:
The invention provides a MDGC apparatus that includes a cryotrapping apparatus capable of cooling at least twice a portion of a chemical sample and provided with a detector device disposed upstream of the cryotrap and allowing identification of the portion of the chemical sample to control the residence time of the latter in the cryotrapping apparatus.
