atomic fluorescence spectrometry (AFS)


In atomic fluorescence spectrometry (AFS), ground state atoms created chemically or thermally in a hydrogen flame or quartz tube furnace, are excited by a beam of light. In difference to AAS measuring the absorbed light, the emission resulting from the decay of the excited state is measured. AFS is a very specific element detection technique but requires a high output, high stability light source.
