Abstract
A method, fast and simple to carry out, is proposed to optimize the in strumental spectroscopic parameters, such as bandpass, lamp current an d monochromator slit height in electrothermal atomic absorption spectr ometry. It is based on the monitoring of the detection limit estimatio n (DLE) variation by using a ''D-optimal'' experimental design. This m ethod is tested on Cd, Mn, Cu and Sn. In comparison with the default o perating conditions, the limits of detection are systematically improv ed.
