An improved glow discharge atomic emission spectroscopy and the apparatus are offered in which the introduction of a rare gas into a glow discharge tube is temporarily cut off and after the inside of the glow discharge tube is maintained at a higher degree of vacuum, a preliminary discharge is executed to remove adsorbed or extraneous substances on the specimen surface, and then the analysis of the specimen surface is performed. The method and the apparatus described in the above are suitable for a quick and simple analysis of the uppermost surface layer of a solid specimen in the direction of depth.
Spectroscopie et appareil améliorés d'émission atomique à décharge luminescente; l'introduction d'un gaz rare dans le tube à décharge luminescente est coupée temporairement, et après obtention et maintien d'un vide poussé à l'intérieur du tube, une décharge préliminaire est appliquée pour éliminer les substances adsorbées ou étrangères à la surface du spécimen, avant l'analyse de celle-ci. La méthode et l'appareil décrits ci-dessus conviennent pour une analyse simple et rapide de la couche la plus superficielle d'un spécimen solide, dans le sens de la profondeur.
