ABSTRACT:
Disclosed is an apparatus and method for using same for atomic absorption determination of volatile, thermally decomposable compounds. The test sample is converted to a gaseous sample in a reaction vessel with an inert gas atmosphere. The gaseous sample in the inert gas is then introduced into a heatable measuring cell arranged in the ray path of an atomic absorption spectrometer. To further assist decomposition, the inert gas is heated prior to entering the measuring cell.
