AJ Instruments Short ARC Lamps

A Xenon short arc lamp provides a continuous emission spectrum across the entire relevant wavelength range used in AAS. Any element and any wavelength can be analyzed simply by software selection. This also includes molecular absorption bands, which can be used for the analysis of non-metals, e.g. the halogens or sulfur. At the same time secondary wavelengths are available to extend the dynamic range towards higher concentrations. The continuous spectrum furthermore enables screening analyses of unknown samples. The light intensity of the Xenon short arc lamp is significantly higher than with traditional light sources (hollow cathode lamps). It provides an excellent signal-to-noise ratio resulting in improved detection limits and better accuracy.
