Heraeus Single-Element Hallow Cathode Lamps

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.
