Abstract
  • A nonflame method for atomic absorption spectroscopy is described. A helical tungsten filament from a commercially available 6-V, 4-A light bulb, heated to :incandescence in an argon atmosphere is used to atomize 2-μl aqueous samples for metals analyses. Studies of two hollow cathode lamp tungsten filament orientations, a modulated light source and associated electronics are described. A rough optimization of system variables in order to improve- sensitivities and limits of detection is also discussed. A time integrated absorbance recording system is described which gives improved results compared to those obtained with the commonly used peak height measure- Ment techniques. Atomic absorption. sensitivities for Mg, Ag, Cu and Ca are 28, 13.2, 3.7 and 0.8 pg, respectively, and corresponding detection limits are 5.2, 16.0, 3.4 and 0.95 pg.
