Analysis of Metals and Alloys for Major Constituents and Trace Elements by Atomic Absorption Spectroscopy
Atomic absorption spectroscopy has proven to be one of the most versatile measurement tools available to the analytical chemist for the characterization of metals and complex alloys for both major constituents and trace elements. Modern instrumentation with digital electronic readout systems and stable, intense light sources has improved the precision of measurements significantly. Sensitivity for most elements used in metallurgical applications is adequate for a precise direct determination; however, for some of the refractory elements preconcentration may be necessary. Most metals and alloys are readily dissolved in common reagent acids or acid mixtures. Standards are then conveniently prepared from stock solutions of the pure elements. Standards should be carefully matched with samples with respect to both cation and anion concentrations to reduce the possibility of interference effects.
