This document describes the working principle of hollow cathode lamps, with particular attention to the improvements made to multi-element hollow cathode lamps and boosted discharge lamps
Hollow cathode lamps are essential components in atomic absorption (AA) analysis systems. This document reviews their relevant characteristics and highlights improvements made over time, with a focus on multi-element and boosted discharge lamps.
The text details the history of lamp development starting from CSIRO in Australia to Agilent Technologies. It explains the construction and working principles of both conventional hollow cathode lamps and boosted discharge lamps, comparing their performance regarding spectral line intensity and self-absorption.
Hollow cathode lamps are essential components used to generate atomic spectral lines required for atomic absorption analysis.
The fill-gas inside the lamp is either neon or argon.
