3d chemical mapping of toners by serial section scanning transmission X-ray microscopy

Abstract

We describe three dimensional chemical mapping of a 2x10x10 micron volume of a toner particle by scanning transmission X-ray microscopy using serial section sampling and computer reconstruction. To our knowledge this is the first example of serial section 3d imaging by soft X-ray microscopy. This is an attractive alternative to tomography when sample density is large and detailed 3-d chemical information requires image acquisition at a number of X-ray energies.
