Investigation of the Hollow Cathode Discharge as an Atomic Absorption Medium

Abstract
A hollow cathode discharge has been studied as a means for vaporizing and atomizing samples for atomic absorption. The design and operational characteristics of the cell are presented with detection limits and precision data for Ag, As, Ca, Cd, Hg, Pb, Se, and Zn. In general, detection limits between 1 and 10 ng were obtained. The present limitation of the method due to the sample holder blank is discussed.
