Photoionisation (PID) lamps are most commonly used in gas chromatography (GC), trace gas monitoring and sample ionisation for mass spectrometry. For example, they can be used to detect leaks in underground storage tanks or for portable gas analysis.
Heraeus hollow cathode lamps have a unique cathode cup system that allows the lamp to reach equilibrium quicker. A special base design ensures a direct connection between cathode pin and wire for maximum reliability.
XERADEX lamps and radiance systems provide vacuum ultraviolet radiation (VUV), which are used, among other things, for surface treatment, ozone generation and the generation of purified water.
It is 4 times higher intensity of VUV.
