Deuterium or Ultra-Violet (UV) Lamps
Anacon supplies a wide range of deuterium lamps to fit most instruments. See our equivalents list to find which lamp is most appropriate for your instrument or send us an email with the details of your instrument and we will figure out which lamp is most appropriate for you.
Applications – UV-Visible Spectroscopy, Spectrofluorimetry UV detectors attached to HPLC instruments, Colourimetry, Refractometry and as a non atomic source for background correction in Atomic Absorbtion Spectroscopy.
Range – A number of configurations are available including different filament voltages, terminal connectors, aperture sizes and brackets to suit many different instruments.
Deuterium arc lamps have the following technical advantages:
Stable Filament – The use of a horizontally mounted filament across two firm short wire supports, reduces mechanical vibration. This avoids the destruction or degration of the emission cathode during shipping or handling which often causes premature lamp failure.
Sputter Shielding – Careful prevention from deposits of materials from the cathode onto the window and discharge cup during running life is achieved by special shielding. This feature assists in decreasing the loss of intensity over the life of the lamp.
Envelope – Use of UV transmitting borosilicate instead of quartz reduces cost and no long term deterioration of the window area occurs (solarisation). No diffusion loss of deuterium occurs.
Lifetime – Each deuterium arc lamp should maintain 50% of initial energy for 1000 Hrs at 300 mA DC.
