Deuterium lamps are used in high-value analytical instruments to test pharmaceutical drug purity, to monitor environmental contamination and to test food composition.
Heraeus Noblelight has released a mercury-free timer and a new power supply for deuterium lamps.
Deuterium lamps are used in high-value analytical instruments to test pharmaceutical drug purity, to monitor environmental contamination and to test food composition.
These applications demand critical performance in terms of reliability, accuracy and reproducibility.
The consistency of the UV radiation from the lamp is an important factor for reliable measurement data.
Modern deuterium lamps meet strict requirements with regard to noise, long-term stability and operating life.
Power supplies should be designed to match the variety of lamp operating conditions to ensure optimum lamp performance.
Consequently, Heraeus offers its own range of power supplies, from bench top laboratory design to fully integratable OEM versions, all developed through its long experience with deuterium lamps.
The PSD 186 R and D deuterium lamp power supply is compatible with virtually all 30W deuterium lamps currently on the market.
The user can select heater voltages of 2, 2.5, 3, 6, 9, 10 and 12V.
In addition the LCD displays allow users to select and monitor their own operating parameters.
The new power supply features very low noise and drift characteristics.
It is equipped with an Ethernet interface and MAC address for remote control via PC.
Heraeus power supplies offer stable electrical parameters and their ignition properties, which protect the lamps, improve operating life and ensure reliable starting.
Heraeus has also released the ETI 300 elapsed time indicator, a small and inexpensive, low power consumption device, designed to measure the operating hours of deuterium lamps and other lamp types.
Because of the new RoHS regulations the use of mercury has become limited for electronic devices such as timers.
The new Heraeus ETI 300 mercury-free time indicator complies with the RoHS directive.
The hours are shown on a four-digit LCD display.
It works on a purely electronic basis and was developed as a replacement for elapsed time indicators based on mercury electrolysis.
