Title (EN) ANALYTICAL FURNACE HAVING PREHEATING AND CONSTANT TEMPERATURE SECTIONS
(FR) FOUR ANALYTIQUE COMPORTANT DES SECTIONS DE PRECHAUFFAGE ET A TEMPERATURE CONSTANTE
Abstract:
(EN) A furnace having a first preheating section (10) protecting outwardly from a constant and higher temperature secondary section (11) and means for moving a sample through the preheating section into the second section. Preferably both sections are graphite and the movement is by rapid movement of a rod (14). The furnace is intended for atomic spectroscopic analysis.
(FR) Four comportant une première section de préchauffage (10) protégeant d'une température constante et plus élevée la partie externe d'une section secondaire et un mécanisme pour faire traverser à un échantillon la section de préchauffage et l'amener dans la seconde section. Les deux sections sont de préférence en graphite et le mouvement est conféré par un mouvement rapide d'une tige (14). Le four est destiné à l'analyse spectroscopique atomique.
