Hollow Cathode Lamps - Agilent
www.agilent.comsource with atomic absorption (AA) spectrometers. A single or multi-element hollow cathode lamp is required for each element to be determined using the AA technique. The key requirement for the hollow cathode lamp is to generate a narrow emission line for the element being determined. The emission line
