Abstract

PURPOSE:To perform double sheathing and extend the life of a cuvette by blowing an inert dry sheathing gas directly to a heating element and filling the sheathing gas also in a structural body incorporating the heating element. CONSTITUTION:An inert dry sheathing gas such as gaseous argon is injected directly from th ceramic nozzle 6 of the chamber 14 of an atomization furnace for atomic absorption analysis incorporating a cuvette 8 grasped by graphite electrodes 7, 7', one of which is movable, to the vicinity of the maximum temp. part of the cuvette 8. At the same time, the atmosphere in the chamber 14 is also substituted with the gaseous argon, whereby double sheathing is accomplished, and the sustained presence of oxygen and water near the maximum temp. part of the cuvette, the remaining of steam during drying of the specimen, and the inflow of air from the electrode movable part to the chamber are prevented. As a result, the cuvette is prevented from deteriorating, and the life of the cuvette is extended.
