ABSTRACT:
An atomic absorption spectroscopy photometer comprising: sample atomizing means for heating to atomize a sample; a plurality of light sources disposed at a like number of light flux incidence positions for causing light having required wavelengths to enter the atomized sample; means for measuring the degrees of light absorption of a plurality of elements contained in the sample by detecting the fluxes of light which have passed through the atomized sample; a plurality of holder means for holding the plurality of light sources, the plurality of light sources being larger in number than the plurality of the light flux incidence positions; and means for setting required ones of the light sources of the plurality at the corresponding light flux incidence positions by moving the holder means.
