Since the friendly takeover of Cathodeon and IST Spectral Technologies, Heraeus Noblelight offers a large variety of high-quality hollow cathode lamps. Heraeus hollow cathode lamps are fitted as originals by many of the worlds foremost atomic absorption instrument manufacturers and as replacements by many end-users.
The Heraeus lamp program includes approx. 70 single- and more than 120 multi-element lamps in the versions "Standard" and "Perkin Elmer" and, therefore covers a wide range of instruments. Where appropriate, these lamps are available with data-coded bases, allowing the instrument to automatically identify the lamp element. In addition, a range of lamps specifically designed for use with Smith-Hieftje background correction systems is available.

Heraeus 37 mm hollow cathode lamps are suitable for most commercial atomic absorption spectrometers: Analytik Jena, Baird Atomic, Beckman, Chemtech Analytical, Corning-EEL (Evans), Fisher Jarrell-Ash, GBC, Hitachi, Instrument Laboratory, Jenoptik, Unicam, Rank-Hilger, Scintrex, Shandon Southern, Shimadzu, Thermo Jarrell-Ash, Varian, Zeiss.
AAS instruments manufactured by Perkin Elmer require lamps with a diameter of 50 mm (2 inches). Non-coded lamps come with a 9-pin connector, coded versions have a 12-pin connector.
Coded Hollow Cathode Lamps
We offer a large variety of data-coded single- and multi-element lamps for instruments manufactured by Perkin Elmer, Thermo-Unicam and Varian. Data coded lamps incorporate in the base or connector a unique electronic configuration which the instrument recognises and uses to set default operating parameters for the routine analysis of that element. The electronic configuration of the data-coding is specific to each instrument manufacturer and is not interchangeable.
Warranty
Heraeus hollow cathode lamps are warranted to emit spectra for a period of 24 months from the date of despatch or 5000 mA hours usage, whichever occurs first. HCLs for Smith-Hieftjte systems are warranted for 500 hours with the exception of the elements As, La, Sb and Tl (150 hours), Bi, Cs, Na, Si and Ti (200 hours), Te and K (300 hours).
