www.whitman.eduatomic absorption instrument was made commercially available in 1962. Since then, there have been a series of rapid developments that are ongoing in atomic and emission spectrometry including a variety of fuels and oxidants that can be used for the flame, the replacement of prisms with grating monochromators, a
Analytical Methods for Atomic Absorption Spectroscopy
www1.lasalle.eduAll modern Perkin-Elmer atomic absorption instruments are capable of measuring both atomic absorption and atomic emission. It is important for the operator to understand the processes that occur in each technique. Every element has a specific number of electrons associated with its nucleus. The normal and most stable orbital configuration of an ...
