WebThe approaches to use for disposal of used hollow cathode lamps depends a little on where you are located. Within the USA, Agilent promotes a program run by Veolia that enables used lamps to be returned for recycling and safe disposal. Veolia break down the lamp to enable recycling of the components and disposal of the chemical residues. WebAs it uses a hot cathode to achieve stable and reliable arc discharge, approximately 10 sec for preheating is required before starting the discharge. A deuterium lamp requires a large and complex power supply, making it more expensive than a halogen lamp.

WebOther articles where hollow cathode discharge lamp is discussed: spectroscopy: Line sources: Other examples are hollow cathode lamps and electrodeless lamps driven by microwave radiation. If specific atomic lines are desired, a small amount of the desired element is introduced in the discharge. A hollow-cathode lamp (HCL) is type of cold cathode lamp used in physics and chemistry as a spectral line source (e.g. for atomic absorption spectrometers) and as a frequency tuner for light sources such as lasers. An HCL takes advantage of the hollow cathode effect, which causes conduction at a lower voltage and with more current than a cold cathode lamp that does not have a hollow cathode.
