Scanning Electron Microscope
The scanning electron microscope (SEM) is capable of taking images of objects and materials with magnifications ranging from 100 to over 100,000 times their original scale. It is particularly suitable for examining rough surfaces as, unlike a conventional optical microscope, the entire surface is in focus at the same time. By using the X-rays emitted from the material under investigation, it is possible to find out which chemical elements are present and whereabouts they are in the material. We have utilised this process of material analysis to help us build a more complete understanding of What's In My Stuff?
