A history of atomic absorption spectroscopy 665 The method was not long in being put to practical application. In 1950, Severinghaus and Ferrebee determined Ca in serum, urine, and other fluids by flame photometry [309]. A laboratory intercomparison study conducted by the TMC, using soil and water samples from sites contaminated by uranium mill tailings, indicated large discrepancies in analytical results reported by participating laboratories for arsenic, selenium, molybdenum, and vanadium. However, because the determination of potassium and sodium is the most common use made of flame photometry and the area of application is so well established, very few references on this subject are cited. 201 Want to read; 12 Currently reading; Published 1968 by Elsevier Pub.

Agricultural chemists were responsible for some of the developments leading to the extensive use of flame emission and of atomic absorption spectroscopy in research, soil testing, and plant analysis laboratories. Note # 3. Of the different techniques for atomic emission spectroscopy (AES) only those which use a flame or an ICP are of any interest for analysis of biomedical specimens. as described for the molecular techniques in UV-Vis Absorption spectroscopy. Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. The sample is excited (raised to a high temperature), causing the emission of light. It is felt that both these fields are potentially superior to conventional flame photometry, particularly with regard to sensitivity and freedom from interference.

Two examples are cited. In short, flame photometry (FP) is an atomic technique which measures the wavelength and intensity of light emitted by atoms in a flame resulting from the drop from the excited state (formed due to absorption of energy from the flame) to lower states. Also included in this tabulation are the relative spectral interferences of other elements of the group studied which interfere with the emissivity measurements of the bands and lines listed. If you continue browsing the site, you agree to the use of cookies on this website. Thus the sample is the source of photon emissions through relaxation via resonance fluorescence (Section 1.2.2). the wavelength of the emitted light is a function of the energy of the excited electrons, so each element has a characteristic set of wavelengths. In Atomic Absorption Spectroscopy, the production of atomic vapour by flame is the most important phase. Atomic absorption spectroscopy is also called as Absorption Flame Photometry. Atomic absorption occurs when an atom in the ground state absorbs light energy and transitions to a higher energy level.
