Table 53  Steps for Area analysis 
  Step  Examples/hints 
1 
Prepare the sample   
2 
Move the stage into Eject position and put the 
sample to the crosshairs of the stage 
 
3  Move the stage into Load position 
 
4  Start the vacuum pump, if required 
 
5  Select the workspace for Point analysis 
 
6 
Move the sample into focal plane with Autofocus, 
control if the sample is flat over the line scan area 
 
7  Switch to the workspace for Area analysis 
 
8 
Define the area for the map in the image   
9 
Set the pixel distance or number of pixels in the 
workspace Area  
 
10 
Set the tube parameters in device area X-ray tube, 
set for highest count rate to get a small statistical 
error  in short measurement time per pixel  
 
11 
Set the measurement time and stage mode with 
the downward-facing arrow next to Acquire 
It is recommended to use short measurement times 
per pixel and measure in several cycles to 
accumulate distributions with high spatial resolution 
 
 
12  Start the measurement with Acquire
