Popis:	In direct-current-arc spectrochemical analysis using a direct reading spectrometer, an alkali metal line which has a suitable sensitivity and is free from interference must often be rejected because of self-reversal in the required concentration range. The simplicity of alkali metal spectra greatly restricts the choice of analysis line, so that a means of utilizing self-reversed lines in direct photometry, where line-width methods such as those of Gerlach and Rollwagen1 and Coheura2 are not applicable, would be valuable. The analytical use of the ground state (UI) K 7664.9 A line, which readily develops a strongly reversed profile, as shown in Fig. 1, is described in this note.
