Comparison between Electrode-less Discharge Lamps and Hollow Cathode Lamps as light sources in AAS

Electrode – less discharge lamps provide high intensity (!0-100 times) and narrow emission lines which lead to higher signal – to -noise ratios over the lines obtained using hollow cathode lamps. Our earlier article Types of light sources in Atomic Absorption Spectroscopy covered the essential features of the two commonly used light sources – hollow […]
