Deuterium (D2) HPLC Detector Lamps
We have more than 300 deuterium lamps available for HPLC detectors by Agilent Technologies, PerkinElmer, Varian, Heraeus Noblelight, Waters and more than 60 other manufacturers. Find the right lamp for your equipment using the drop-down-menus. All lamps have a guaranteed minimum life span of 1,000 to 2,000 hours. Replacing the lamps is really easy – contact us to find out how you can save a lot of money.
We offer lamps from numerous brands, including Agilent, Waters and Heraeus Noblelight. As an equivalent and low-priced alternative, we carry lamps of our own brand Altmann Analytik. If you are using instruments not listed on our website or if you need a lamp that is not displayed here, feel free to contact us.
Deuterium lamps for HPLC detectors are gas discharge lamps in which a small amount of deuterium is lit up by electrons. The emitted UV spectrum of deuterium lamps starts from the UV wavelength range (185-400 nm) to the visible spectral range (400-800 nm). The lamp body itself is made of synthetic quartz as normal glass hardly allows UV radiation to pass through. The quartz also absorbs radiation below 170 nm. To ignite the deuterium lamp, it is first heated with a low DC voltage, easily recognisable by an orange glow. The actual ignition is then initiated with a high-voltage pulse. Electrons are emitted from the filament, which now absorb so much energy as they pass through the electric field, at the same time ionizing other gas molecules and thus releasing more electrons. This results in a build up of stable gas discharge.
Deuterium lamps emit an almost continuous light spectrum starting from the UV wavelength range (185-400 nm) to the visible spectral range (400-800 nm). Due to their high stability, they are particularly suitable for spectroscopic examinations. The high-quality deuterium lamps from Heraeus Noblelight, Agilent Technologies, and Altmann Analytik all have operating lifespans between 1,000 to 2,000 hours. All lamps have either quartz glass or UV glass bulbs. We offer lamps (e.g. D2 deuterium lamps) for devices from all established manufacturers such as Agilent lamps, PerkinElmer lamps, Varian lamps, Waters lamps and many more.
