Heraeus Hollow Cathode Lamps

Heraeus Hollow Cathode Lamps

Hollow cathode lamps consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. In addition various mica discs, ceramic sheaths and glass shields assist in alignment and insulation. Heraeus hollow cathode lamps are primarily used in instruments for atomic absorption spectroscopy (AAS). Heraeus hollow cathode lamps are designed for optimal performance and characterised by good chemical sensitivity and spectral response, combined with stable light output and low noise.
