Analytical glow discharges running in pure Ar are commonly used for direct solid analysis and depth profiling. The analytical results can be very significantly affected by molecular gases (H_2, N_2 and O_2) which are very often present in the discharge for various reasons. One approach to understanding of the processes involved when a small amount of H_2 is present in the discharge is to investigate the spatial intensity distribution of emission lines and the effect of H_2 on this distribution. Different processes take place in different parts of the discharge volume and affect thus different lines in various ways. The aim of this study was to investigate the effect of H_2 on spatial intensity distribution of different Fe and Zn emission lines but only Fe results are discussed in this paper.
