Die Atomemissionsspektrometrie , oft auch optische Emissionsspektrometrie oder Flammenspektroskopie genannt, ist eine Methode der Atomspektroskopie. Sie wird zur quantitativen und qualitativen Analyse von festen, flüssigen und gasförmigen Proben eingesetzt. Die Methode basiert darauf, dass angeregte Atome eine für das chemische Element charakteristische elektromagnetische Strahlung aussenden und somit Informationen über die Zusammensetzung der Probe liefern. Die Anregung der Atome erfolgt über eine externe Energiezufuhr, z. B. über eine Flamme, einen Lichtbogen, einen Funken oder ein induktiv gekoppeltes Plasma , und der Überführung in den Plasmazustand.
