Performance of Lead Hollow Cathode Lamps for Atomic Absorption Spectroscopy

Abstract
The use of neon as filler gas in lead hollow cathode lamps provides considerably more light energy than was available with earlier lamps. The spectroscopic performance of these lamps is reported as a function of gas fill, lamp current and spectral bandpass The detection limit for the lead analysis is shown to be 0.03 ppm lead in aqueous solutions with the new lamps and particular atomic absorption instrumentation
