Mapping Workflow
Similar to spectroscopy, EFTEM is a simple workflow to help you enhance contrast, map and analyze chemicals or elements.
-
Find the region of interest you want to map.
-
Insert and center an appropriate objective aperture.
-
Align the zero-loss peak.
-
Focus and stigmate the image.
-
Take a thickness map to decide if the sample has the correct thickness to proceed.
-
Move to an energy offset appropriate for the type of map you want to acquire.
-
Focus and stigmate at the energy loss.
-
Acquire maps.
-
Adjust manual settings if needed.
Follow these step-by-step instructions for the above workflow when you use Gatan Microscopy Suite® (GMS) software.
