EDAX EDS Manual

(1) After this menu item has been selected, the cursor changes
to an I-beam.
(2) Click on the spectrum at the point where the text is to be
inserted. An edit box appears and the comment is typed
directly into the box. The text will scroll if not all text
can be displayed in the edit box.
(3) Once all text has been entered, press Enter to insert the
text into the spectrum. Up to 32 characters can be entered
for each text item and up to 10 comments can be added to a
spectrum.
� A comment can be changed or deleted from the spectrum by choosing
the Select Text menu item, then clicking on the existing comment
in the spectral window. The text will be displayed in the edit
box and can then be changed. To completely delete the comment,
delete all text in the box and press Enter.
Peak ID
� You should select the Peak ID control panel by clicking on the
correct button (the left-most button out of the right-most group;
the one that shows a spectrum with a “?”).
� You can then click on “Auto” for an auto-peak ID (the same can be
done by clicking on the “ID” button on the button bar). You may
need to modify some of peaks identified. To remove an element,
select the element from the “Saved Elem” list box and click the
“Delete” button.
� To add an element manually:
(1) Type the four characters in “Element” box (e.g. SiKa,
AgLa, or K Ka, etc.).
(2) Pick an element that is near the element you want to
add from the “Saved Elem” list and click “Z-” or “Z+”
until the element of interest appears in the “Element”
box, then click “Add”.
(3) Click the cursor on the peak that you want to identify
in the spectrum, then click on the choice from “Pos
Elem” box and click “Add”.
� After performing the peak identification procedure, there are
commonly some vertical lines on the spectrum that indicate the
position of the last peak or element requested during the peak ID
step. If the spectrum is to be printed, these lines will sometimes
print with the spectrum (in older versions of the software) and this
is rarely the desired result. To remove the line(s), first select
the “Peak ID” control panel, then click on “View” and “Element
Marker”. A new method to remove these markers is to do a right or
left mouse click in the spectrum area.
HPD
� This button (found in the Peak Identification panel) is used to
calculate and display the background and deconvolution without
displaying any quantification results. The user need not go to the
Quantification Control Panel to calculate the background and
deconvolution. The HPD (in light blue) relies on the element list
and correct kV when modeling.
� HPD is used for confirming the present element list. A user can
click on the HPD button to see what the spectrum should look like
with the elements identified. If the HPD does not match the
spectrum then adjustments can be made to the element list and the
HPD button clicked again. These steps can be repeated until the HPD
