Abstract
An objective function, based on signal-to-background ratio measurements, with a variable step-size simplex procedure is used to optimize conditions for multi-element determinations by inductively-coupled plasma/atomic emission spectrometry. When a typical 10-elements solution was used, the optimization produced small but significant improvements in limits of detection. The ease with which optimal multi-element instrumental conditions were identified is attributed to the compact analytical zone of the plasma produced when a wide-bore (2 mm i.d.) injector tube is used.
