Abstract
L'invention concerne un four d'atomisation (1) chauffé transversalement ou longitudinalement, constitué d'un matériau carboné, destiné à la spectrométrie d'absorption atomique et comprenant un four tubulaire (17) dans lequel se trouve un porte-échantillon (2). Le perfectionnement consiste dans le fait que le porte-échantillon possède sur sa face inférieure, en vue de sa fixation dans le four, un tourillon ou un pied central (4) qui est fixé dans un évidement correspondant sensiblement à la forme du tourillon et se trouvant au centre de la paroi intérieure du four et sensiblement en regard de l'ouverture d'introduction des échantillons. Le porte-échantillon et le four sont constitués d'électrographite. La surface accessible au gaz du porte-échantillon et du four est revêtue de pyrocarbone. Les deux parties précitées sont métallisées par cette couche de pyrocarbone de manière définie. Le porte-échantillon s'étend de préférence sur la plus grande partie possible de la longueur du four. La face supérieure du porte-échantillon présente un évidement en forme d'auge (5) pouvant contenir jusqu'à 50 µl de solution d'analyte. Le poids du porte-échantillon est réduit grâce à des dispositions structurales. Lors de son fonctionnement, le four d'atomisation présente une bonne stabilité à long terme de la sensibilité et de la reproductibilité, ainsi qu'une plage d'énergie de concentration linéaire élargie sur le plan de l'extinction intégrée dans le temps.
