which has a maximum multiple response for the following experimental
conditions: atomization temperature: 1980 C, modifier
mass: 2.89 lg, pyrolysis temperature: 641 C and pyrolysis time:
7.01 s. This model was calculated using real values and only significant
terms are being expressed. It has no lack of fit.
Based on these results, the experimental conditions chosen for
the ET AAS method were as follows: atomization temperature:
2000 C, modifier mass: 3 lg, pyrolysis temperature: 640 C and
pyrolysis time: 7 s.
