Hollow cathode lamp

Stable light output and low noise characteristics for Atomic Absorption Spectrometry.

hollow cathode lamp

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.
