  Working Principles
Click to ViewIn AAS, liquid sample is aspirated to become aerosols of fine particles (nebulization), Flame vaporizes the aerosols (atomization), Elevated temperatures in a flame or furnace changes the chemistry of atoms. Temperature affects the ratio of excited and unexcited atoms.Beer’s law is used to calculate concentration of specific element.

  Applications
  User Instructions
Concentration of metals in water, sediment and biotic community. In laboratory routinely analysed concentrations of Cd, Cu, Fe, Mn, Pb and Zn by flame mode. Arsenic by hydride generation mode. Water samples to be preserved with adding conc. HNO 3 after filtration. Fresh biological samples may be ice preserved or dried. Then all the samples are digested with suitable acid to bring metals into free solution phase. All the samples to be passed through filtration (Whatman 42 or equivalent) before feeding into instrument. The processed samples are now ready for analysis in AAS.For analysis of arsenic in hydride generation mode, the acid for processing of water samples is HCl.
