ELECTRO-THERMAL ATOMISER FOR ATOMIC-ABSORPTION SPECTROMETER

摘要

FIELD: chemistry.;SUBSTANCE: electro-thermal atomiser for an atomic-absorption spectrometer contains a pair of water-cooled cylindrical holders of ring graphite electrodes with a heated graphite cylindrical basin placed between them and a cylindrical protective casing coaxially enclosing it with a radial dosing opening, passing inside the basin. The protective casing is provided with a reflective surface, with the space between the protective casing and the basin being separated by an inert gas stream, in addition, the protective casing can have a window in the reflective surface for remote control of the basin temperature.;EFFECT: increase of the efficiency of electric energy application, consumed for heating the basin.;5 cl, 5 dwg
