This review emphasizes sample preparation for atomic spectroscopy. The present and future tendencies for sample preparation also involve on-line dissolution, extraction of the analytes, speciation, solid. Since the atomic orbitals have discrete or specific energies, transitions among them have discrete or specific energies.
Therefore, atomic absorption spectra consist of a series of "lines" at the. Atomic absorption spectroscopy serves the above mentioned objective by enabling the determination of Copper and Iron concentrations in spirits, gin, whiskey, rum, vermouth and other alike beverages.
