Atomic Absorption Spectrophotometer (AAS)


Atomic Absorption Spectrophotometer (AAS)
  Instrument Details  
Make : Thermo ( Solaar AA Series)
Model : M6 MK2
Specification :

        Estimation of cationic micronutrients (Zn, Cu, Fe and Mn ) and heavy metals ( Pb and Cd) in ppm to high concentration level. Atomic-absorption spectroscopy quantifies the absorption of ground state atoms in the gaseous state. It is a technique for measuring the concentration of various elements in the sample through their absorption of light. It is a relatively simple and reliable technique which uses absorption of optical radiation by free atoms for determining the contents of different elements.

  Working Principles   

        Atomic absorption spectroscopy is based on the principle that when a beam of electromagnetic radiation is passed through a substance, the radiation may either be absorbed or transmitted depending upon the wavelength of the radiation. The absorption of radiation would bring about an increase in the energy of the molecule



The energy gained by the molecule is directly proportional to the wavelength of radiation. The increase in the energy of the molecule leads to the electronic excitations where electrons jump to higher energy levels. A particular wavelength that a given molecule can absorb depends upon the changes in vibrational, or rotational or electronic states.
