Click “OK” to validate, wait a few seconds and the table “Standards” should indicate
the currently selected standard. Verify this list is correct. You can also open the tab
“Element Setup” in the bottom-left panel: all elements that have now a standard
defined will be highlighted as purple (see
Fig. 23 ).
WARNINGS on standards selection:
•
You MUST select standards acquired at the same VOLTAGE as your analyses
(usually 15 kV)!
•
If multiple standards are available such as Fe
2
O
3
and FeS
2
for Fe at the same kV,
choose the one the most similar to the type of phase to be analysed.
•
The standardization on the EDS holds well for months and it is tested periodically.
However, if you think it needs a new standardization, ask for assistance.
•
If you have already acquired data and you change the list of standards, you will have
to reprocess all your data, and this can be time consuming… It is better to choose
the right standards BEFORE acquiring any quantitative data!
