Abstract

The invention relates to optical instrment engineering. It is suggested that a liner solid state detector (photodiode array detector, charge coupled device, charge transfer device) that is positioned along the image of entrance slit of the monochrometer be used in an atomic absorption spectrophotometer. This will improve the analytical performance of an atomic absorption spectrophotometer--lower the detection limits, extend the range of concentrations to be measured, increase the reproducibility of measurements by taking into account the temporal and spatial non-uniformities of the analyte distribution over the atomizer volume and will simultaneously provide atomizer walls and of the platform temperatures.
