Measurements of the absolute intensities of discharge gas and trace elements/isotopes can help to understand the ionization mechanism and contribute to the reduction in uncertainty related to the relative sensitivity factor (RSF).

It is likely that plotting of variation in quantification of discharge gas can be used to optimize and select discharge condition that can eventually help for RSFs determination.

AbstractThe Relative Sensitivity Factor (RSF) in Spark Source Mass Spectrometry analysis was found to be dependent on the number and duration of previous sparking periods. This dependency becomes very strong when dealing with volatile elements. By statistical analysis of experimental RSF values it was found that there is a linear correlation between In (RSF) of some trace elements and their boiling temperature. This correlation fails when dealing with volatile elements and carbon. It was found that elements with a large diffusion coefficient have a large RSF.
