The Atomic Fluorescence Spectroscopy (AFS) technique is widely used for determination of hydride forming elements and Mercury analysis. The technique provides an alternative to the conventional method of connecting a hydride generator to an Atomic Absorption Spectrophotometer (AAS). Due to the high intensity Hollow Cathode lamp source and low baseline noise offered by this technique, the usable sensitivity is greatly improved offering very low detection limits (ppt).

The AFS instrument fulfils the analysis by means of simultaneous detection, accurate sample introduction and stable furnace temperature control complementing the more widely used AAS flame/graphite systems.
