This paper discusses the parameters which influence the operation of hollow cathode and deuterium lamps. Examples are given of how parameters can be selected in order to improve the quality of analytical results. Aspects of deuterium lamp operation for background correction are also covered.
This document provides an overview of the construction and design characteristics of hollow cathode lamps used in atomic absorption spectroscopy. It details the roles of the cathode material, filler gas (typically argon or neon), zirconium anode, and glass envelope selection based on spectral transmittance requirements.
| Filler Gas Type | Argon or Neon |
|---|---|
| Anode Material | Zirconium |
To generate a narrow emission line of the element being measured with sufficient spectral purity and intensity.
Neon has a higher ionization potential, which produces greater signal intensity.
