Measuring Elements by Atomic Fluorescence
Description
Atomic fluorescence spectroscopy measures elements by detecting the light atoms give off after they are excited by electromagnetic radiation. The atoms are first placed in a flame, furnace, or plasma. They absorb energy, become excited, and then release that energy as they return to their original state. The emitted light is...

Transcript
En la espectroscopia de fluorescencia atómica, o AFS, las muestras atomizadas son irradiadas por radiación electromagnética para causar transiciones electrónicas, y se mide la radiación de fluorescencia emitida.
El instrumento AFS tiene una fuente de luz de alta intensidad, un atomizador, un selector de longitud de onda y un detector. Las...
