AAS (Atomic Absorption spectroscopy) When performing elemental analysis using an atomic absorption spectroscopy, the sample needs to be first decomposed into free-state atoms (atomization process) before it can absorb the radiation emitted by the light source system for subsequent analysis. a.) In atomization process, there is no denying that we should take advantage o the atomizer. The atomization technique can be divided into flame and flameless methods. (a-1.) When it comes to flameless atomizer, graphite furnace is a classic example. Please review the information discussed in class about graphite furnaces. (a-2.) Please try to compare the advantage and disadvantage of the flame and flameless atomizers. (a-3.) When using flame atomization, different elements have different optimal measurement heights, and the same element may yield different measurement results at different heights. Explain why
