HTL Hollow Cathode Lamps are single-element spectral sources designed for atomic absorption spectroscopy (AAS). Each lamp produces characteristic emission lines for a specific element, providing the narrow-line spectral output required for elemental analysis. The HTL range includes 50 single-element lamps covering commonly measured metals, metalloids, and other elements in a standard 38 mm (1.50 in.) lamp format.

Applications

HTL Hollow Cathode Lamps are designed for elemental analysis by atomic absorption spectroscopy. They are suitable for routine laboratory analysis, analytical method development and validation, research, quality-control testing, and other AAS procedures requiring an element-specific hollow cathode spectral source.
