JEOL has developed a new EPMA(Electron Probe Microanalyzer), that continues a long history of EPMA development extending over neary a half century. The JXA-8230, designed for user-friendly operations, provides for a complete range of analyses through a new, simple to use, PC-based interface. The high-accuracy and fast speeds offered by the JXA-8230 are a result of its sophisicated hardwre developed from JEOL's EPMA technologies refined over neary 50 years. The JXA-8230 is powerful, next-generation, analytical tool that fully meets all of the requirements of an EPMA.
