Radiation Sources:

In atomic fluorescence, an excitation could be performed both along with continuous as well as along with monochromatic sources, that consequently affects the fluorescence intensities accessible and the freedom from stray radiation. While a continuous source like as tungsten halide or a deuterium lamp is used as basic source, it has the benefits in which the multielement determinations could be taken up. Therefore, because of their low radiant densities, detection power is not fully exploited. Alternatively, while line sources like as hollow cathode lamps and electrodeless discharge lamps, are used, these gives much higher radiance but we cannot do multielement analysis. Lasers are being used as the radiation source within modern AFS instruments along with the benefits of high radiant power. Now let us learn about these radiation sources.
