There is one additional function to improve the statistics of a line scan. With the definition of the
line scan it is possible to enlarge the “thickness” of the line with the + key and reduce it with the –
key, respectively. In that case the intensities of all pixels perpendicular to the line are
summarized, which increases the intensity and improves the statistics of the line scan.
6.9.6 The Phases tab
6.9.6.1 Working with the Phases tab
Phases summarizes areas of similar composition and displays them in same colors. This allows a
fast overview for parts of the sample with similar composition and can be used as a sum
parameter. A phase image is created based on the chemical information stored in every pixel of
an acquired map (ROI element map or HyperMap).
Phase offers three methods to generate a phase image:
The Histogram and Clusters methods operate automatically
Objects offers the possibility of supervising the process (see 6.9.6.2).
All three methods work based on:
the number of elements chosen (e.g., via the periodic table) and selected (within the
clipboard) for the mixed map image within the Map result tab,
the order the elements are displayed within the clipboard under the Map result tab.
In general, the best results are achieved for a phase image when the elements that are most
useful for distinguishing between different phases are selected to be displayed first within the
clipboard.
Before using the AutoPhase function, it is recommended to activate the option Automatic
update (via the downfacing arrow next to the AutoPhase button). This is especially helpful when
experimenting with different methods and parameters as the phase image will update after every
change. A phase image is produced by clicking on the AutoPhase button.
For a generated phase image, Phase determines the area occupied by each phase. If necessary,
phases can also be merged into a single phase. If the phase image was produced based on a
HyperMap, sum spectra can be generated for each phase and can be quantified.
