摘要: With the aim of extending working concentration range for tin in graphite furnace atomic absorption spectrometry (GFAAS), analytical performance several non-resonance lines this element were studied, using atomization from tube wall and platform. The use these enables to be extended amounts up 140 times greater than upper linear limit most sensitive line without degrading precision (measured as relative standard deviation) measurement.
