Day 1 Afternoon
WDS Practical Session
Basics of WDS:
Explain/Show the three scan modes
Scan several elements in each mode
Intelligent scan
Show multiple element scans/overlay on EDS spectrum
Optimize Height for a new sample area; use fixed WD, then Z-Stage
Show the element configuration table, then how to edit it.

Note: For this training, customers are strongly encouraged to bring their own samples, either conductive or carbon coated, due to we do not have a low vacuum SEM. In case of WDS quantification, please also bring the standards either compounds, e.g. SiO2 for determining Si, or pure standards.
