摘要：

Spatially resolved measurements of ion kinetic energies and densities have been obtained in an inductively coupled plasma (ICP) by mass spectrometry (MS). Because of changes in the plasma potential, ion kinetic energies varied as the ICP was sampled in different locations. These changes were found to be similar to those reported by others, but caused problems in the interpretation of the measured ion densities. Nevertheless, spatial profiles compared favorably to those obtained by laser-excited fluorescence in the ICP, and axial distributions of BaOH+, BaO+, Ba+ and Ba2+ correlated well with the behavior of ICP-MS signals that occur when the inner gas flow rate is varied. © 1990.
