Analytical applications

ChemiSEM image of "Salt and Pepper" imaged at 15 kV with the T1 in-lens backscatter detector and integrated EDS ChemiSEM EDS detector. The image on the left shows backscatter contrast of the particles on a carbon sticky tab. The image on the right shows the live, automatically applied elemental image for sodium (Na), representing the salt and oxygen-rich pepper in blue (O), and (C) showing the carbon sticky tape. Note the similarity of the phases in backscatter, yet the elemental analysis clearly shows the phase separation. This extra color can help you distinguish between phases that could otherwise be confused.
