Helium-Glow Photometer for Picomole Analysis of Alkali Metals

Gerald G. Vurek 1 and Robert L. Bowman 1

1 Laboratory of Technical Development, National Heart Institute, Bethesda, Maryland 20014

The low-power electricglow discharge in helium can excite efftctively the characteristic emission lines of sodium and potassium. The helium-glow photometer used to generate the glow and measure the light is a relatively simple apparatus; it can be used to analyze samples containing 10-14 mole or more of sodium and potassium. Overall precision of the apparatus and method is 5 percent or better.
