Analysis of element of minute parts

By using microbeam analysis, JFE-TEC undertakes elementary analysis of minute parts.

  • By means of an electron probe micro-analyzer (EPMA) and energy dispersive X-ray analysis by scanning electron microscopy (SEM-EDX), it is possible to conduct qualitative analysis and quantitative analysis mapping of minute parts of several µm or less in size.
  • By means of field emission-electron probe micro-analyzer (FE-EPMA), it is possible to conduct quantitative analysis of minute parts 100 nm in size. By means of energy dispersive X-ray analysis by ultra-low voltage scanning electron microscopy (ULV-SEM-EDX), it is possible to conduct 30-nm order analysis.
  • By means of energy dispersive X-ray analysis (EDX) and electron energy loss spectroscopy (EELS) equipped on transmission electron microscopy (TEM), it is possible to conduct qualitative analysis and quantitative analysis mapping of minute parts several nm or less in size.
  • Using transmission electron microscopy with Cs corrector (Cs corrector STEM), ultra-fine atomic scale analysis in 0.1-nm order is possible.
  • Using electron energy loss spectroscopy (EELS), it is possible to analyze the chemical bonding state of elements. State analysis using plasma oscillation and interband transition is also possible.
