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. Heraeus offers the widest selection of single- and multi-element coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry.

Heraeus 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. Lamps for use with Smith-Hieftje background correction can also be offered:

• 70 single-element lamps
