For the bowl by atomic absorption spectroscopy, without the flame and its method of manufacturing

摘要

A body made of carbon, in particular by electrographite, is covered with a protective layer of pyrolytic graphite, which is activated in turn by the application of a carbon layer is very low grade of orientation (soot) or by a mechanical treatment in order to make the rough. This activation causes a reducing agent in the sample to be analyzed, so that the protective effect of the layer of pyrolytic graphite is maintained. / p & & p & application: cup for the atomic absorption spectrometry.
