Atomic and Ionic Fluorescence in an Inductively Coupled Plasma Using Hollow Cathode Lamps Pulsed at High Currents as Excitation Sources

Abstract

Hollow cathode lamps pulsed at high currents were used as atomic and ionic fluorescence sources to excite atoms and ions in an inductively coupled plasma. Atomic fluorescence was measured for Cu, Ag, Zn, Al, Cr, and Mo, while ionic fluorescence was measured for Cu, Cr, Zn, and Sr. Limits of detection for atomic fluorescence were found to be better than those obtained by a commercial atomic fluorescence instrument operated under the same conditions, and calibration curves were linear over a range of approximately 104.
