 Introduction of Analysis & Testing Equipment
 Surface/Structure Analysis Equipment: 03-03--Electron probe micro-analyzer (EPMA)--

JXA-8900RL EPMA-1600
Exterior View (left: JEOL JXA-8900RL right: Shimadzu Corporation EPMA-1600)
 Principle The sample is placed in a vacuum and irradiated with 4nm to 100m electron beams, then the image is acquired from the intensity of characteristic X-rays, backscattered electrons, or secondary electrons generated from the measurement site.
 Usage (1) Element segregation, mapping examination
(2) Comparison of tint between elements
(3) Surface analysis
