Block diagram of atomic fluorescence spectrometry:
The instrumentation for AFS consists of atom reservoir that might be a flame or a furnace etc., a basic source emitting the features absorption radiation of the element being determined, a monochromator (or filter), detector, signal processor and readout device. The basic source is commonly a hollow cathode lamp or a tuned laser. The block figure of the equipment required for AFS is shown below:
