WebFor a ‘‘quantitative ’’ analysis, the intensity of light emitted at the wavelength of the element to be determined is measured. The emission intensity at this wavelength will be greater as the number of atoms of the analyte element increases. The technique of flame photometry is an application of atomic emission for quantitative analysis. WebThe two most common atomizers in atomic absorption spectroscopy are combustion flames and graphite furnaces. We will now discuss in a little more detail the mechanism by which these atomizers work. Combustion Flame Atomizers The following figure gives some idea of the most common type of flame atomizer, complete with the nebulizer and spray ...

WebFlame atomization and (optional) electrothermal atomization are widely used. Flame atomization In a flame atomizer, a solution of the sample is nebulized (formed into a fine mist or aerosol) by a flow of gaseous oxidant (e.g. air), mixed with a gaseous fuel (e.g. C 2H 2), and carried into a flame when atomization (formation of gaseous atoms ...

WebApr 10, 2024 · Sample analysis with ICP-OES is usually safer than FAAS due to the use of inert argon gas as an atomizer instead of a flammable gas, such as acetylene. Not requiring a lamp for each element, simultaneous multi-elemental analysis, and low ppb detection limits are among the advantages that make ICP-OES the favored technique for elemental ...
