Abstract

La présente invention concerne un procédé et un dispositif pour l'enrichissement d'une substance, recherchée à partir d'un échantillon dans un tube de graphite. Procède caractérisé en ce que l'échantillon est vaporisé et est précipité sur la paroi intérieure d'un tube de graphite maintenu à une plus faible température. Procédé applicable à la vaporisation de substances pour une analyse par spectro-photométrie à absorption atomique sans flamme.
