Atomic-Absorption Spectroscopy Prelab

Question #3

The advantage of using a slot burner rather than a cylindrical burner in flame AA spectroscopy is that:

  1. It provides a longer path length and therefore a larger absorption signal.
  2. It is quieter than using a cylindrical burner.
  3. A long narrow flame does not get as hot as a cylindrical flame.
  4. A long narrow flame gets much hotter than a cylindrical flame.
