Do deuterium lamps contain mercury?

How do you dispose of deuterium lamps?

When disposing a deuterium (D2) lamp or halogen (W) lamp, separate them from general waste and handle them as industrial waste. Dispose them so that they will not pollute the environment or negatively affect human body, or ask a professional waste disposal company.

What does a deuterium lamp do?

Deuterium lamps are light source lamps that utilize an arc discharge in deuterium (D2) gas. They emit an intense spectrum in the UV region and have feature of unrivaled stability compared to other UV light sources.

When should deuterium lamps be replaced?

When to replace a lamp

If the peaks of interest have a strong signal, in other words, in excess of 100 mAU/mV, then it is reasonable to wait until the lamp fails to ignite until it is replaced. This will typically be 4,000–8,000 hours.

Why do we use deuterium lamps in UV spectroscopy?

(2) Deuterium Lamps

A deuterium lamp requires a large and complex power supply, making it more expensive than a halogen lamp. However, it is one of the few continuous spectrum light sources that is stable in the ultraviolet range. The deuterium lamp has a short emission wavelength of 400 nm, or less.

What is the radiation source for UV region?

Sources of UV radiation

IT IS AMAZING:  Is it safe to cover LED lights?

Both deuterium and hydrogen lamps emit radiation in the range 160 – 375 nm. Quartz windows must be used in these lamps, and quartz cuvettes must be used, because glass absorbs radiation of wavelengths less than 350 nm.

How do I check my lamp hours in HPLC?

You can find “update variables display“, that will update numeric information of it on lower screen. You will find Lamp used hours.
