The direct analysis of solid samples via glow discharge (GD) sources further extends the utility of PSMS. The desire to rapidly perform sensitive determinations while simultaneously collecting an ever-greater amount of chemical information motivated the evolution from simple bulk determinations of elemental composition to sophisticated methods that offer micro-, spatially resolved, and time-resolved analyses. In this suite of methodologies, the sample concentration often changes during the analysis, and these transient methods place new demands on instrumentation. The continued success of PSMS depends on its ability to adapt to these challenges, and alternative mass analyzers, such as time-of-flight mass spectrometry (TOFMS), have been explored as a means to meet such demands. |
