Abstract

L'invention concerne la détermination de la concentration du soufre dans un échantillon. Elle se rapporte à un appareil qui comprend un four 11 qui brûle l'échantillon qui forme essentiellement de l'anhydride sulfureux qui est fixé, dans le réacteur 13, par de la pyridine, le mélange étant alors tiré par un titrimètre automatique 15 et le résultat est affiché par un dispositif 22 de lecture. Application à la détermination de la concentration du soufre dans les charbons.
