Using the Method Editor
This section describes how to use the Method editor and how to set up a quantification method
for the automatic quantification of multiple spectra. Setting up a quantification method is also
important to turn a HyperMap into a QMap (see section 5.18).
Step
Example/hints
1
Select the Spectra, Objects, Line scan
or
Mapping workspace.
In the Line scan and Mapping workspaces,
spectra are accessible under the
Spectrum
tab.
2
Click
on the
button and
select
Load… to load a quantification
method
.
Select a quantification method (eg. Default,
Oxides, Standards or TEM
). Alternatively
drag and drop a
quantification method from
the project to the spectrum chart.
3
Click on the button and
a) Select Edit…
This opens
the METHOD EDITOR to set up
a
method before performing the quantification.
b) Double click on the method name next
to the button.
4
Use the Elements menu to
a) choose how peaks will be labelled
Use spectrum elements will use element
markers that you have previously set in the
spectrum via the
icon.
Use list elements
will only use the elements
that you have select
ed (bold) in the periodic
table within the method editor.
Search additional elements
will perform an
AutoID (see also step 4c).
b) access element properties
Double click or right click on an element to
access the element properties dialog. Use
this dia
log to set Deconvolution only or to
change spectral line for quantification.
c) change settings for the AutoID (when
using the
Search additional elements
option
).
Set Minimum concentration to an
appropriate value to avoid that the AutoID
finds too many
peaks (especially when
spectra are noisy). Elements with a gray
background in the periodic table are excluded
from the AutoID. To include them click on the
specific element.
5
Use the Element overview list menu to
display non
-default settings for selected
elements.
Use this list to change or review element
parameters.
6
Use
Background settings
menu to
select background fit areas and fit model
The background fit area can be set to
A
utomatic or Preset.
