Hollow Cathode Lamps (HCL)
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, 37mm and 50 mm lamps in the industry. They are designed for optimum performance by combining:
Good chemical sensitivity High spectral response Stable light output
Low noise characteristics Long operating and shelf life
Applications
Atomic Absorption Spectroscopy
Atomic Fluorescence Spectroscopy
Multi wavelength laser tuning
Laser output stabilisation (Optogalvanic effect) Multi component analysers
Medical analysers
