Atomic Absorption Methods for the Direct Analysis of Metals and Alloys

While atomic absorption methods of spectrochemical analysis have found a wide range of application, they have been almost entirely confined to the analysis of solutions. Solid samples for analysis have required prior solution. In recent months the situation has been transformed, and it has been demonstrated that some important metals and alloys can be analyzed directly by atomic absorption methods, which can be applied to the precise determination of major constituents and of trace impurities.
