Farah, K. S.; Sneddon, J. Optimization of a simultaneous multi-element atomic-absorption spectrometer. Talanta 40(6):879-882 (1993).

Abstract:

A variable-size simplex procedure was used to optimize the operating conditions for the simultaneous determination of Cu, Zn, Mn and Fe by flame AAS. Seven factors were optimized including the slit width, the air-to-fuel ratio, the height above the burner head and the four hollow-cathode lamp currents. Results confirm that multi-element atomic absorption requires a compromise in operating conditions.
