Abstract: The voltage-current and spectral characteristics of a high current (up to tens of amperes)microsecond pulsed hollow cathode lamp has been studied. The intensities of the atomic and ionic lines emitted by the pulsed HCLare greatly enhanced as compared with those emitted by the same lamp with DCsupply, and the enhancement factor is much greater for the ionic lines (104) than for the atomic lines. This implies that the HCMSP HCL could be used as a convenient and inexpensive source for ionic fluorescence spectrometry.
