Abstract

Générateur d'étincelles dans le vide pour l'analyse spectrographique dans l'ultraviolet d'un échantillon jouant le rôle d'anode, ayant une cathode annulaire coaxiale coopérant avec l'anode et une électrode auxiliaire disposée à distance faible de la cathode pour la formation d'étincelles d'initiation. L'électrode d'initiation a sa partie opératoire en regard de la surface latérale de la cathode et en retrait par rapport à la face frontale de la cathode coopérant avec l'échantillon pour la formation de l'étincelle principale. Les parties en regard de la cathode et de l'électrode d'initiation sont munies d'un jonc amovible en légère saillie par rapport au corps de la cathode et de l'électrode d'initiation.
