Principle of atomic fluorescence spectrometry, Chemistry

Principle of atomic fluorescence spectrometry:

In AFS, the analyte is converted within gaseous atoms in the ground state using a appropriate atomization technique. These are then excited through features monochromatic radiation from a basic source like a xenon lamp or a hollow cathode lamp, electrodeless discharge lamp or a tuned laser.  A fluorescence radiation emitted through the decaying atom is then measured within the direction perpendicular to in which of the incident radiation. The position and intensity of the emitted radiation forms the primary of qualitative and quantitative analysis through atomic fluorescence spectrometry.
