Abstract
The evaluation of accuracy and efficiency of the frequency-modulated s imultaneous Atomic Absorption Spectrometry (FremsAAS) has been extende d to an arrangement with EDL as light sources. Fundamental calibration s have been worked out for As, Se and Sb using a graphite furnace as w ell as hydride generation in combination with a heated quartz tube as atomization unit. The characteristic data are in good agreement with r esults obtained by conventional single-channel AAS instruments. Determ inations in three standard reference materials with different complex matrices resulted in complete agreement with the certified values.
