Abstract
The device described was developed with the two following essential conditions in mind: - absence of any pollution during the sampling operation and the transfer to the analysis apparatus; - simultaneous extraction of several samples, each one remaining representative of the sodium in the circuit. The sampling is therefore carried out completely in a vacuum in a Pyrex-glass apparatus, this limiting the sodium temperature to a maximum of 240 deg. C. The samples are in the form of bulbs sealed in vacuo containing 2 to 3 grams of sodium each. The analysis of the oxygen by the amalgamation technique, carried out on samples obtained by this method show a very satisfactory reproducibility for concentrations of under 20 ppm. (authors) [French] Le dispositif decrit a ete mis au point compte tenu des deux imperatifs essentiels suivants: - absence de toute pollution pendant les operations de prelevement et de transport vers l'appareil d'analyse; - obtention simultanee de plusieurs echantillons, chacun restant representatif du sodium du circuit. A cet effet, le prelevement est effectue entierement sous vide dans un appareillage en verre Pyrex, ce qui limite la temperature du sodium a 240 deg. C. Les echantillons se presentent sous la forme d'ampoules scellees
