Frequently Asked Questions

Hollow cathode lamps are primarily used in instruments for atomic absorption spectroscopy (AAS). Further derivatives of the fundamental technology extend the applications to include atomic fluorescence spectroscopy, multi wavelength laser tuning, laser output stabilisation (optogalvanic effect), multi component analysers, environmental analysers, and medical analysers.

Data coded hollow cathode lamps incorporate a unique electronic configuration in the base or plug which the instrument recognizes and sets default operating conditions for the routine analysis of that element. The parameters may be overridden by the operator if desired to suit the specific requirements of the analysis.

The standard 50mm lamps for Perkin Elmer instruments have a 2” (50 mm) diameter and a dedicated electrical connector. They are entirely compatible with Perkin Elmer instruments and utilise the long established features of the standard range.

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 in which the discharge is highly constrained within the cathode of a specific metal, resulting in a unique line spectrum.
