ABSTRACT:
A method and apparatus for simultaneous multielement atomic absorption analysis, comprising use of a continuum source and a high resolution echelle polychromator modified for wavelength modulation, and a high speed data acquisition system (SIMAAC). The method and apparatus is capable of measuring as many as 16 or more elements simultaneously with either flame, electrothermal or other means of atomization. Double beam operation and dynamic background correction are achieved on all channels. Linear dynamic range of up to six orders of magnitude can be achieved for each channel.
