Quantitative Analysis of Metallic Ions Associated with Fluid Inclusion

The authors developed previously a new technique of the analysis of fluid inclusion in mineral of the size less than 100 μm and also reported some results in mineral samples taken from several ore deposits[1]. The inclusion fluid is frozen by cooling, to avoid rapid evaporation of the liquid under vacuum at the time when the ion beam breaks the wall of the inclusion. Since Na ion is a major constituent in almost all inclusions, the intensity of each ion is compared to that of Na. the relative intensity is used to estimate the content of each ion using the relative intensities obtained from the synthesized aqueous solution containing each element at different concentrations.
