This paper introduces a set of analytic methods of fluid inclusion composition, including mainly the ICP-MS and PIXE methods for analyzing the liquid-phase composition of bulk fluid inclusions, the LA-ICP-MS methods for analyzing liquid-phase the composition of separate inclusions and the LRM and FT-IR methods for analyzing the gaseou-phase composition of separate inclusions. These methods greatly raise the level of analyzing the fluid inclusion composition. But there are still some problems.
