Heraeus 1-element 5QN/Zn-A (5QNZn-A ) Hollow Cathode Lamp, Zinc Zn, 50 mm PerkinElmer Lumina/Aanalyst coded, 4pin, Without Cable

Hollow cathode lamps (HCL) are discharge lamps designed for use in Atomic Absorption (AA) instruments. They consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. Noblelight offers the widest selection of single- and multielement coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry.

Noblelight hollow cathode lamps are available both for OEMs and as a replacement lamp by discerning users the world over. The range includes standard lamps and data-coded versions for PerkinElmer and ThermoFisher atomic absorption spectrometers.

Single-Element Lamps

The Heraeus catalogue includes 70 single-element lamps in standard 37 mm (1.5 inch) and 50 mm (2 inch) diameters to fit almost any AA instrument. All cathode materials are selected from the highest purity available – usually 99.99 % or better – to ensure high spectral line intensity, stability and low noise with good analytical sensitivity. The window material is selected to achieve the optimum transmission of the primary spectral lines of the cathode element. Borosilicate glass is used for wavelengths over 350 nm, and high quality quartz for shorter wavelengths.

Standard 50 mm Lamps

Perkin Elmer Instruments are unique in requiring hollow cathode lamps with a 2” (50 mm) diameter, and a dedicated electrical connector. Heraeus has developed a full range of such lamps for direct use in Perkin Elmer instruments utilising the long established features of our standard range but making the necessary processing changes to ensure they are entirely compatible to these instruments.
