The chemical phase analysis of layered structure

In many cases, further processing element surface analysis to obtain a clearer sample image is good.We are the quantitative surface analysis of stratified sample presentation.The first picture shows the quantitative surface analysis of mixed graph elements in the sample.The whole picture look very "noisy".In this picture, we defined the three interested or by a representative of the area, they are the two rectangle and a smaller circle area, used to display the test program.

Autophase function can be found in "Objects" (district) mode.It can be used in the main component analysis to define the areas for reference, to find in the picture composition similar areas, and these areas are divided into the same phase.The results are shown in the picture.The second picture can be divided and positioning zinc and Cd content in different phase.By line scan and point analysis leads to the surface of carbon pollution is assigned as the third phase.On the left side of the grey area is located in the area of interest, compared with that of bricks and the gray areas are "unallocated", its composition and identified phase is different.And the most the right side area also contains carbon.
