Flame Aas Atomic Absorption Spectrometer for Metal Elements

The Agilent 4210 MP-AES has high sensitivity, detection limits down to ppb levels and is faster than conventional flame Atomic Absorption (AA) for a typical multi-element analysis. Best of …

Instrumental Chemistry Chapter 10 Atomic Emission Spectroscopy History and Theory of Atomic Absorption Spectroscopy As the name implies, Atomic Absorption is the absorption of light by free atoms Advantages of AA Determination of 68 metals Ability to make ppb determinations on major components of a sample Precision of measurements by flame are ...

Chemical Monitoring and Management – Section 3 + Onwards notes Atomic Absorption Spectroscopy Describe the use of AAS in detecting concentrations of metal ions and assess its impact on the scientific understanding of the effects of trace elements A calibration curve is plotted using samples with known concentrations (on a very small scale such as ppm) versus absorbance (read-out).

The different interferences that are encountered in atomic absorption spectroscopy are : - Absorption of Source Radiation: Element other than the one of interest may absorb the wavelength being used. - Ionization Interference : the formation of ions rather than atoms causes lower absorption of radiation .This problem is overcome by adding ionization suppressors.
