A Background Correction Technique for Furnace or Flame Atomic Absorption with Double Beam Spectrophotometers

摘要: Using furnace atomic absorption an optical method for reducing the effects of background absorption, especially with solid samples, is discussed. The system suitable both and flame absorption. With Cu, Co, Cr, Mg, Mn, Al, Dy hollow cathodes no blank reading was recorded. Calibration curves Ag were obtained. Both liquid samples run. An employing a Glan–Taylor calcite polarizer used. A Beckman model D. B. used to compare polarized beams from cathode continuous source. Sensitivities ranged about 10−11 g 10−10 g/ml samples.
