EFFECT OF GRAPHITE FURNACES DEGRADATION ON THE ATOMIC ABSORPTION SIGNALS
Abstract
Time dynamics of the working characteristics degradation of longitudinally heated furnaces for spectrometers with electrothermal atomization of the sample in the presence of compounds of tungsten, zirconium and palladium used as chemical modifiers has been studied. Visual changes in the state of the investigated furnaces are discussed and the loss of their carbon material during the experiment is shown. The atomic absorption signals of silver and copper recorded at different stages of degradation for unmodified and modified furnaces are analyzed. An explanation of the reasons for accelerated damage to the pyrographite coating and subsequent destruction of the polycrystalline graphite base for furnaces subjected to modification is suggested.
