A Comparison of Atomic Absorption with Other Spectrochemical Methods

Source

The objective comparison of related spectroscopic methods of analysis is discussed. Capability factors considered are: (a) scope of application, (b) sample preparation requirements, (c) sensitivity and limit of detection, (d) precision, and (e) accuracy. Economic factors considered are: (f) instrument cost or availability or both, (g) operational costs, (h) operator training requirements, and (i) time available for analysis. Methods considered are atomic absorption, atomic fluorescence, flame emission, arc-spark emission (photographic and direct reading), X-ray emission, and spark source mass spectroscopy. The method capability comparison of factors (c) through (e) is based primarily on the characteristics of the analytical calibration curve. A method for comparing the economic factors also is suggested.
