Abstract
A atmospheric pressure capacitively coupled plasma high intensity spectral lamp. The lamp generates atom line and ion line spectra from a substance to be analyzed. The lamp comprises a hollow means adapted for containing and sustaining an atmospheric pressure capacitively generated plasma discharge, a first electrode connected to a radio frequency power supply, electrically insulated from the plasma and enclosing at least a portion of the hollow means, and a second electrode constructed of the substance to be analyzed, connected to a radio frequency power supply, the electrode penetrating into the plasma discharge and being capacitively arranged with the first electrode.
