The emission occurs when sufficient energy (which may be thermal, light or electrical) is provided to excite a free atom or ion to a higher unstable energy state (the atomic absorption process). Atomic Absorption Spectroscopy 4 Spectroscopy (ICP-OES), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), have left Atomic Absorption (AA) behind. For a given value of S, the term with maximum L has lowest energy. Overview • In atomic spectroscopic methods, the analyte must be converted into the appropriate chemical form to emit or absorb radiation.

Figure 2 shows a diagram of an atomic absorption spectrometer with a graphite furnace. • Analyte atoms in solution are aspirated into the excitation region where they are desolvated, vaporized, and atomized by a flame, discharge, or plasma. Atomic Spectroscopy Comparison of Interferences and Other Considerations Other Considerations • ICP-OES and ICP-MS are multi-element techniques favored when there is a large number of samples and cost is not a concern 34. Atomic spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. Element concentrations of a millionth (ppm) or one billionth part (ppb) of the sample can be detected. Atomic spectroscopy can result in emission (light radiation), absorption (light extinguishment) or a combination of both (atomic fluorescence). Atomic Spectroscopy W. C. Martin and W. L. Wiese National Institute of Standards and Technology Gaithersburg, Maryland 20899 Originally published as Chapter 10 in Atomic, Molecular, and Optical Physics Handbook, G.W.F. (Rephrased from Sec. Atomic absorption spectroscopy has become one of the most frequently used tools in analytical chemistry. Therefore, performing atomic spectroscopy on most samples involves the utilization of an atomization source, which is a device that has the ability to convert molecules to atoms. In atomic Emission the sample is atomized and the analyte atoms are excited to higher energy levels. Note: Links are not underlined on this page to improve readability.

Since unique elements have characteristic (signature) spectra, atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is applied for determination of elemental compositions.It can be divided by atomization source or by the type of spectroscopy used. a) Radiation is absorbed by non-excited atoms in vapour state and are excited to higher states b) Medium absorbs radiation and transmitted radiation is measured c) Colour is measured d) Colour is simply observed. Total angular momentum . Agilent Atomic Spectroscopy instruments feature technologies at the forefront of innovation. This finds less application as the characters of most substances are dependent on the molecular nature and not just atoms in it. Principle of Atomic Absorption /Emission Spectroscopy 15.1 ATOMIC EMISSION-THE FLAME TEST When a small amount of a solution of a metal ion is placed in the flame of a Bunsen burner, the flame turns a color that is characteristic of the metal ion.
