| • | Assumptions:
(i) Beer's law holds for the |
|||||||
| atoms
in the flame or graphite furnace, and |
||||||||
| (ii)
the concentration |
||||||||
| • | of
atoms in the flame or furnace is |
|||||||
| proportional
to the concentration of analyte |
||||||||
| in
the sample. |

| • | Calculations:
The usual calibration curves |
|||||||
| or
standard addition problems. |
