Abstract:

The inert gas-shielded tungsten arc was used to detect and monitor air contaminants in inert gases and to excite spectra for the four halogen gases. In this note some persistent lines are listed and some quantitative data are presented for fluorine and chlorine in (helium and helium-argon) inert gas shields. Known concentrations of Freon 12 and Freon 14 in helium were used as the source of fluorine-chlorine and fluorine, respectively.
