Quantitative EDS of Electron Transparent Samples
5.13.1
Standardless Cliff-Lorimer Quantification
This guide describes the steps of standardless quantification of electron transparent samples.
Step
Example/hints
1
Load or create a standards library
containing theoretical Cliff
-Lorimer
factors.
Follow section 5.11.2.
2
Select
the or
workspace and
The following workflow also applies to any
spectrum chart available in the ESPRIT
software
, e.g. also within in the Mapping
workspace to quantify complete maps.
a) a spectrum
Follow section 5.7.
b)
Use the Spectrum chart icon to
open a spectrum
.
Optionally, drag and drop a spectrum from
the
Project into the spectrum chart. The
spectrum chart in the
Mapping workspace
can also be used.
3
Cli
ck on the
button and
select
Load… to load a quantification
method
.
Select a TEM quantification method based on
Cliff
-Lorimer. Alternatively drag and drop a
quantification method from the project to the
spectrum chart.
Two different quantification
meth
ods can be loaded, the active one is
displayed in bold.
4
Make sure that geometrical EDS
detector and HV parameters of spectrum
and Cliff
-Lorimer factor database
(standards library) match.
If the information message
“Cliff-Lorimer /
Zeta factor: Wrong p
rimary energy in
standard
s library” pops up, update the
standard
s library as described in 5.11.2.
5
Click
on the
button and
select
Method mode.
Interactive method
Automatic method.
6

Click
on the button an
d
select
Edit…
Use the method editor to set up or edit a
quantification method before
performing the
quantification.
For details see section 5.12.1.
* step can be omitted
7
Start quantification by clicking the
button.
If quantification is set to automatic ( ), the
quantification results appear in
the spectrum
list (see section
5.8 step 1f).
If quantification is set to interactive (
),
proceed with step 8.
8
Edit quantification parameters in the
quantification dialog
.
The left dialog part has the same functionality
as the method editor. All changes have an
immediate effect on the quantification results
displayed in the result table.
Refer to section
5.12.1.
