5.11.2 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. These 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 service. 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
standards 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, Azimuth angle, Tilt angle, Beam
entrance angle. They should match the values
of your microscope/detector configuration
(see step 2).

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.
