Sample Stabilization to Preserve Chemical Identity

  • Patrick Echlin

9.1 Introduction

In this chapter the process of sample stabilization is more complex. Not only do the procedures have to retain structural integrity, but they also have to retain and localize their chemical components for subsequent analysis. In addition, the stabilization procedures may also have to facilitate recognition of some chemical component. These four requirements, retention, recognition, chemical analysis, and stabilization are conjoined and should always be considered together.
  • Before discussing these procedures it is appropriate to briefly recall the general differences between the topographic (image) contrast mechanisms and the compositional (atomic number) contrast mechanism used in SEM and x-ray microanalysis.Topographic information (structural images) is provided by the secondary electrons (SE) and the backscattered electrons (BSE) signals.

  • Compositional information(chemical analysis) is provided by the BSE and x-ray photons (XRP). The physical parameters and...
