UV LampThe Model 629 hollow cathode UV lamp from McPherson Inc. is a flow-controlled, windowless broad-spectrum source that emits ionized gas emission lines with little or no absorption by neutral gas.

Computer-controlled gas flow and constant current power supply improve stability for better spectroscopy. The Model 629 produces excited atoms and ions, which emit electromagnetic radiation at wavelengths characteristic of the gas flowing through the system. It is similar to inductively coupled plasma atomic emission spectroscopy systems. Since there is no limiting window, this UV source works in the more energetic range of wavelengths from double ionized helium at 30 nm up to the visible light range.

The lamp can simultaneously introduce and ionize samples. Molecules of sample media are broken into charged ions after colliding with the electrons and charged ions in the lamps plasma. They emit radiation at characteristic fingerprint wavelengths of the elements involved. The relative intensity of emission indicates concentration of an element within the sample.
