Über Agilent Technologies

Agilent Technologies ist einer der führenden Hersteller in den Bereichen Biowissenschaften, Diagnostik und angewandter Chemie. Mit den hochwertigen HPLC-Systemen schafft der amerikanische Hersteller eine sehr gute Basis für zuverlässige Analytik und die vertrauensvollen Daten, die aus dieser hervorgehen.

In über 110 Ländern aktiv, verfügt Agilent über ein breites Sortiment im Bereich HPLC. Dabei handelt es sich nicht nur um moderne HPLC-Systeme, sondern auch zahlreiches Zubehör und viele Ersatzteile für bestehende Modelle.

HPLC-Sortiment von Agilent

In HPLC applications, deuterium lamps are considered consumables and must be replaced as soon as their performance declines. While the lamps themselves are uniform in construction, they differ in device-specific mounts. Therefore, compatible WICOM Perfect Light® Deuterium Lamps can be seamlessly integrated into the respective HPLC systems, even if they are not produced by the original equipment manufacturer, provided that the mounts and specifications are compatible.

In the WICOM Shop, you will find the appropriate deuterium lamp for any device, regardless of whether it is a modern or older model. Our WICOM Perfect Light® lamps offer precise fitting and extended lifespan due to their superior quality. Additionally, we offer original spare parts and deuterium lamps from esteemed manufacturers like Agilent, Thermo Fisher, Waters, Shimadzu, Hitachi, and Merck.

Expert-Tipp

Caution is advised when handling deuterium lamps, especially avoiding direct contact with the light exit window, as fingerprints can obstruct UV radiation.

Moreover, shortwave UV light is potentially harmful to the retina, making safety precautions essential when changing lamps.

How does a deuterium lamp work?

Components:

The lamp body of a deuterium lamp is always made of specialized synthetic quartz alloys, since ordinary glass would absorb most of the UV radiation.

Ignition:

To ignite a deuterium lamp, it is first heated with a low DC voltage, recognizable by a faint orange-red glow. A high-voltage pulse then initiates the actual ignition. Electrons are emitted from the filament, which, when passing through the electric field, gain enough energy to ionize additional gas molecules, releasing more electrons. This process leads to a stable gas discharge.

Wear and Replacement:

After approximately 2,000 hours, part of the filament evaporates and deposits on the inner surface of the glass body, absorbing most of the UV radiation. Fingerprints have a similar effect, so lamps should never be touched at the light exit window. Additionally, due to the diffusion of the filling gas into the glass body, the ignition spark may no longer suffice to sustain stable deuterium emission. At this point, it is time to install a new lamp.

Where are deuterium lamps used?

Deuterium lamps are essential in high-performance liquid chromatography (HPLC) and other chromatographic techniques for detecting compounds based on their absorption in the UV range. The high spectral purity of deuterium lamps enables the precise detection of even the lowest concentrations.

Applications:

• HPLC: Determination of impurities and active substances.
• Analyte detection: High precision in UV absorption measurement.
• Reproducibility: Stability of the light source ensures consistent results.

How long do deuterium lamps last?

Deuterium lamps burn very stably and have a long service life of 1,000 to 2,000 hours. Newer models, such as those from Heraeus Noblelight, the world leader in deuterium lamp manufacturing, can last well over 2,000 hours in use.

The degradation of the filament results in deposits on the lamp glass, which dampen UV radiation. Additionally, aging of the gas inside the lamp can lead to ignition issues, affecting functionality. To maintain accurate detection in HPLC, it is essential to regularly inspect and replace the lamp when necessary.
