Hollow Cathode Lamps for AA

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. We 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.

Our hollow cathode lamps are used by discerning scientist globally.  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

  • More than 120 multi-element lamps with up to seven combined elements

  • Customary diameters 1 ½” and 2″

  • Low-current and high-current versions

  • Standard and encoded lamps

  • Long life due to higher gas volume

  • Clear signals and low distortion due to special cathode technology

  • Can be used for almost any AA instrument
