Annotatsiya

A new complex laser analytical spectrometer operating synchronously in the atomic beam regime and in the flame regime is developed. Analytical potentialities of the spectrometer are demonstrated by the example of determining sodium and calcium content in standard solutions and aluminum alloys. Processes of thermal atomization of Ca and Na in vacuum and the effect of the basis of a sample on the element determined are studied. Efficient excitation via Rydberg states is realized for these elements. The contents of Ca and Na in aluminum alloys are determined at levels of 10−2 and 10−3%, respectively.
