McPherson’s windowless, hollow cathode UV lamp Model 629 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. This windowless hollow cathode UV lamp is versatile; it 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.
