Uses of Deuterium Lamps :

We supply Deuterium Lamps for HPLC and UV-Vis Spectrometers purpose. Apart from that Deuterium Lamps can be used ideally in pharmaceutical companies for testing purpose for:

• Atomic absorption spectroscopy (AAS)
• Thin film measurement
• Thin layer chromatography (TLC)
• Laboratory light sources

A deuterium lamp uses a tungsten filament and anode placed on opposite sides of a nickel box structure designed to produce the best output spectrum. Unlike an incandescent bulb, the filament is not the source of light in deuterium lamps. Instead an arc is created from the filament to the anode, a similar process to arc lamps. Because the filament must be very hot before it can operate, it is heated for approximately 20 seconds before use. Because the discharge process produces its own heat, the heater is turned down after discharge begins. Although firing voltages are 300 to 500 volts, once the arc is created voltages drop to around 100 to 200 volts. ^[1]
