Propst diagram

Mikhail and Robens [4] discuss the techniques available with reference to the Propst diagram. Figure 6.1. Only a few of the many possible combinations of probe and response, indicated in Figure 6.2, are in common use. Photons and electrons are the most important, as both probes and responses, for obtaining information about the electronic structures of the surface atoms of samples. 

The Propst diagram [4] summarises the probes that may be used (the inward arrows) on the sample (the circle) to produce the various responses (the outward arrows) which provide information about the sample. 

Surface analysis techniques are categorized in Table I. Figure 1, often called a Propst diagram, illustrates the probes and emitted species that can be measured in many of the new techniques for surface analysis. More than 40 of the possible combinations have been explored many others have not yet been tried. Figure 2 presents an approximate comparison of the various techniques with respect to their depth of analysis. Only the techniques that have shown success or show promise for use in biomaterials characterization will be considered in more detail in this review.
