Increasing of the accuracy of materials composition measurement by atomic fluorescent method

摘要

The two techniques of accounting of scattered light in atomic fluorescence analysis are considered. The first technique is based on using in one light source the effects of broadening of the spectral line of hollow cathode tube and self-absorption within the quartz balloon in high-frequency discharge. The second technique is based on the difference between the hollow cathode tube linewidth at the beginning and the end of the pulse of excitation current.
