The Effect of Sources/Absorber Width in Continuous Sources Atomic Absorption Spectophotometric†

Abstract

The effect of source/absorber width in Continuous Source
Atomic Absorption Spectroscopy (CSAAS) profiles is studied to
increase the intensity of atomic absorption lines. The effect of slit
width in source/absorber profiles is studied too, to obtain some
sharp absorption lines. Some good results are obtained when
σ_s << σ_a. Some good results are achieved for lanthanide elements.
The absorbances obey Beer's law and the calibration curves are
linear in a good range of concentration.
