Flameless AAS provides a means to increase flame AAS sensitivity, by up to 200 times. Types of Interferences in Atomic absorption Spectroscopy Classification, causes and remedies. Generally, spectral interferences are more common in emission spectroscopy than in absorption spectroscopy. absorption spectrometry for which the terms electrothermal atomic absorption spectrometry, electrothermal AAS and the abbreviation ETAAS are defined. They arise when the absorption line of an interfering species either overlaps or lies so close to the analyte absorption line that resolution by the monochromator becomes impossible. Atomic absorption spectroscopy is an absorption spectroscopic method where radiation from a source is absorbed by non-excited atoms in the vapour state. 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. Chhit. An alternative way of getting a broadened source signal to pass through the flame is known as the Smith-Hieftje method (named after the investigators who devised this method). 41 Spectral Interference This refers to overlap of analyte signals with signals originating from other elements in the sample or with signals due to the flame or furnace. Atomic absorption spectroscopy is ideally suited for the analysis of trace and ultratrace analytes, particularly when using electrothermal atomization. An atomic fluorescence spectrometer is capable of measuring samples containing both hydride-forming elements and Mercury at a parts per trillion (ppt) level using the unique vapour hydride generator. For minor and major analytes, sample are diluted before the analysis. Chem. Analytica Chimica Acta 1972 , 59 (2) , 197-208. •Atomic absorption spectroscopy is one of the most widely used techniques for the determination of metals at trace levels in solution. Various types of spectral interferences in atomic absorption spectroscopy were investigated. 2. Spectral line interferences in atomic absorption spectroscopy. • Absorption or emission of an interfering species overlaps or lies so close to the analyte absorption or emission that resolution is not possible. Source emission of multiplets and other Interferences from aqueous leachates and digestates are so great, however, that flameless AAS has found application mainly after organic extraction. The high sensitivity and reliability of Aurora’s series of Atomic Fluorescence Spectrometers is ideal for elemental analysis in a variety of research and industrial sectors. • It has also been applied in optical emission and atomic fluorescence Atomic spectroscopy includes a number of analytical techniques used to determine the elemental composition of a sample (it can be gas, liquid, or solid) by observing its electromagnetic spectrum or its mass spectrum. •Its popularity as compared with that of flame emission is due to its relative freedom from interferences by inter element effect and its relative insensitivity to various in flame temperature. Chapter 9 Atomic Absorption and Atomic Fluorescence Spectrometry Atomic Spectroscopy Atomization is by far the most critical step in atomic spectroscopy. DOI: 10.1021/ac50001a022.
