Definitions

  • the gas sample present in the infusion pump 16 was metered to or injected in the gas chromatograph 1, by moving the piston 25 upwards at a speed such that 10 ml of gas sample were delivered to the refrigerating trap in the injection system of the gas chromatograph per minute through the conduit 28, the second switching valve 13 and the conduit 14.
  • the cryofocused sample was injected by leading the carrier gas (helium) through the refrigerating trap, which was quickly heated to 150°C.

Abstract

L'invention concerne un procédé d'enrichissement d'un ou de plusieurs composant(s) volatil(s) contenus dans un flux gazeux préexistant et à doser ce(s) composant(s) dans un flux gazeux limité, pour un instrument d'analyse. Ce procédé est caractérisé en ce que le flux gazeux est aspiré ou poussé à travers une première soupape de commutation dans un adsorbeur dans lequel le(s) composant(s) volatil(s) est/sont adsorbé(s), puis le flux gazeux libéré dudit ou desdits composant(s) est entraîné hors du système à travers au moins la première soupape de commutation; une quantité mesurée de gaz inerte est ensuite introduite à travers la première soupape de commutation dans l'adsorbeur chauffé au moyen d'une pompe à infusion, puis entraînée à travers cet adsorbeur de sorte à retenir le ou les composant(s) volatil(s), puis retournée à travers la première soupape de commutation et à travers une seconde soupape de commutation dans la pompe à infusion, puis le gaz inerte ainsi que son ou ses composant(s) volatil(s) sont libérés dans un instrument d'analyse à travers la pompe à infusion et la seconde soupape de commutation. L'invention concerne également un dispositif permettant de mettre en oeuvre ce procédé.
