The capabilities of inductively coupled plasma atomic-emission spectrometry—some conjectures and refutations

Abstract

Inductively coupled plasma atomic-emission spectrometry (ICP-AES) is among the most powerful and versatile methods available for elemental analysis. However, there are some clearly identifiable shortfalls when its capabilities are compared with those of an “ideal” technique. In addition, use of the method exposes weaknesses both in current chemical techniques and in chemometric appreciation. Most of the shortfalls could be effectively remedied by users of ICP-AES rather than manufacturers.
