3.2. Instrumental parameters optimization
The following parameters were evaluated for the different
tissues, aiming to obtain compromise conditions for the different
samples: pyrolysis and atomization temperatures, use of chemical
modifier and slit width.
In order to optimize the instrumental parameters the samples
used were from a no intoxicated animal. The tissues were then
fortified with Pb2þ in order to obtain sample solutions with
5.0 mg L1 Pb2þ.
