Lead analysis by flame atomic absorption spectroscopy

  1. Explain what happens to the analyte sample when it is aspirated into the flame of the AA, including ionization and atomization? (cite all sources used).

2) The flame side of the AA measures concentrations in parts per million range and the furnace side of the AA measures in parts per billion. What is the major difference in terms of sample introduction and electron excitation for these two kinds of the spectroscopy.

3) What are the units of ppm in mass/mass ratio? In mass/volume ratio?

4) What units of ppb in mass/mass ratio? In mass/ volume ratio?
