Definitions

  • the degree of segregation it is possible to use methods other than the laser ICP method. For example, it is possible to determine the degree of segregation by measuring the concentration of elements in a location of interest using chemical analysis or the like and comparing the results of analysis with the results for portions where there is no segregation. It is also possible to determine the degree of segregation by the EPMA method or by the laser ablation inductive coupled plasma mass spectroscopy (LA-ICP-MS) method in which quantitative determination in the laser ICP method is carried out by mass spectrometry instead of by emission spectroscopy.
  • LA-ICP-MS laser ablation inductive coupled plasma mass spectroscopy
