The hollow cathode lamp is a discharge lamp designed for use as a spectral line source 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. Production of hollow cathode lamps is an intricate process that requires expertise in many diverse disciplines including glass blowing, quartz/glass welding techniques, inter-metallic species and metal alloy fabrication, and lamp purification/ stabilization techniques.
