Abstract The potential is measured inside a supersonic jet to obtain fundamental information about the extraction process in inductively coupled plasma-mass spectrometry (ICP-MS). The potential in the jet is of positive polarity and varies with sampling position, plasma power, and aerosol gas flow rate in much the same way as both the potential outside in the plasma and the ion kinetic energy. The magnitude of the potential is comparable to the intercept of a plot of mean ion kinetic energy as… CONTINUE READING
