Frequently Asked Questions

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.

The applications of hollow cathode lamps include atomic absorption spectroscopy (AAS), atomic fluorescence spectroscopy, multi wavelength laser tuning, laser output stabilisation (optogalvanic effect), multi component analysers, environmental analysers, and medical analysers.

The Heraeus hollow cathode lamp product range comprises 70 single-element lamps and more than 120 multi-element lamps of the most varied designs to cover almost all appliances.

A hollow cathode lamp is a gas discharge device that produces a unique line spectrum of a specific metal.

The standard 50mm lamps are non-data coded for all instruments requiring a 2" lamp.
