Abstract
Procédé et dispositif servant à introduire un gaz de référence dans des systèmes de spectromètres de masse isotopique. Ce gaz de référence est introduit dans le système avant une interface de combustion et produit des crêtes de forme gaussienne semblables à celles produites pour des constituants de l'échantillon. Dans un mode de réalisation de l'invention, l'entrée du gaz comprend trois conduits venant en intersection au niveau d'un point d'intersection, ce qui permet à un gaz de référence et à un écoulement secondaire d'un gaz porteur de pénétrer dans l'entrée par l'intermédiaire de conduits séparés et de sortir par l'intermédiaire du troisième conduit avant l'entrée de l'écoulement secondaire dans l'interface de combustion.
