Hollow Cathode Lamps

A Hollow Cathode lamp is an ideal source of spectral line designed for use in Atomic Absorption Spectroscopy Instruments (AAS). The Hollow Cathode Lamp consists of a glass tube containing a cylindrical cathode with element of choice, which when applying voltage through the anode, the inert filler gas is ionized creating plasma from the gas and sputtering the atoms of the cathode, generating a sharp wavelength for the element of choice.

Spectrolamps HCL's offer minimal spectral interference, rapid warm up and stable emission, intense emission of resonance lines at low operating currents, long operating life, saving on consumables. With over 70 single elements and multi-element lamps available, with choice of filler gas.

Hollow Cathode lamps (HCL's) are available in 2 standard sizes, 1.5 inch (37mm) for most instrument manufacturers and 2 inch (51mm) for PerkinElmer instruments. Single and multi-element lamps, non-coded and coded version as a direct replacement lamp for AAS Atomic Absorption Spectrometers. Coded HCL's are available for Agilent / Varian, GBC Scientific and Thermo Fisher / Unicam Instruments and data coded replacement lamps for PerkinElmer Aanalyst range of spectrometers. Hollow Cathode Lamp with Coded recognition, allows the instrument to automatically identify the lamp element.
