Abstract

Two inductively coupled plasma–atomic emission spectroscopy exercises are described for use in an undergraduate instrumental analysis course. The first activity looks at the emission signal produced by two different ionization states of the same element. The ionization states are in equilibrium within the plasma, and by observing the emission signal in different spatial regions of the plasma one can deduce information about the predominant ionic state and see suppression of the emission signal from the minor state. In the second exercise, the excitation temperature of the plasma is measured as a function of the power applied to the plasma induction coils. This temperature derives from the Boltzmann distribution, and can be determined by monitoring the intensity of a series of well-characterized emission transitions that emanate from a single ionization state of the element being observed.
