Maintain Standards Library for Electron Transparent Samples –
Cliff-Lorimer Factors
This guide describes how to check and calculate theoretical Cliff-Lorimer factors for standardless
quantification of electron transparent samples using the standards library dialog.
Step
Example/hints
1
Click the
icon in the bottom left
corner of the
Standards configurator
to
open the
ADMINISTRATION OF
STANDARD LIBRARY dialog.
2
Check the detector geometry parameters
.
These parameters have to match the
parameters of
measured data and/or settings
of your EDS configuration on the microscope.
A spectrum measured with the correct
system settings will also contain the
respective values. Th
ese can be checked in
the file or by double click
on the text line
below the spectrum chart.
The geometry
parameters of a measurement system can be
checked in the
workspace by
clicking on
and should only be
changed by Bruker s
ervice. If the geometry
parameters
do not match, proceed with step
3
. If they match, proceed with quantification
as described in section 5.13.1 or 5.13.2.
3
Use the standards library icon to
a) Load a standards library or
Load a previously saved *.esl file which
corresponds to detector geometry
parameters. Proceed with step 5.
b) Select New to create an empty
standard
s library
The question “Do you want to load a
spectrum measured with corresponding
system settings?” pops up.
i. Select Yes
If you are using the software as Data station
(not connected to a microscope)
. The LOAD
SPECTRUM
dialog pops up. Load a spectrum
*.spx which was acquired with corresponding
detector geometry.
ii. Select No.
If you are using the ESPRIT software
connected to the microscope.
4
Check NEW STANDARD LIBRARY
geometry parameters, enter a name and
click
.
Check or update values of Energy, Elevation
angle, Azimut
h angle, Tilt angle, Beam
entrance angle. They should match the values
of your microscope/detector configuration
(see step 2).
5*
Click on
to review.
The EDIT CLIFF-LORIMER FACTORS dialog
pops up:
Cliff-Lorimer factors for K-, L- and M
-
lines
are listed. Zoom the graph:
left click into
it and use the arrow keys on keyboard.
