Atomic Emission Spectrometry - an overview ScienceDirect Topics
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 … fltcs
