Abstract
With the aim of extending the working concentration range for tin in g raphite furnace atomic absorption spectrometry (GFAAS), the analytical performance of several non-resonance lines of this element were studi ed, using atomization from the tube wall and from the platform. The us e of these non-resonance lines enables the working range to be extende d to amounts of tin up to 140 times greater than the upper linear limi t for the most sensitive line without degrading the precision (measure d as the relative standard deviation) of the measurement.
