13.Click OK .
The new product file is set up and the related measurement application is normalized.
What you can do next
You can now perform standard free measurements.
You can also calibrate your measurement application. Use a sample of your electrolyte solution,
which was externally analyzed. Do not make up a solution for calibration.
19.5.4 Setting up a Def.MA for the Solution Analysis by yourself
If you have installed the SUPER software, you can create a Def.MA for the solution analysis by your-
self.
The usage of the SUPER software requires deep knowledge of the physics of x-ray fluorescence and
the functionality of the instrument.
Alternatively, you can request a new measurement application from FISCHER. FISCHER offers a
professional service for the creation of customer’s Def.MA.
Structure of a Def.MA for the Solution Analysis
The typical structure of a Def.MA for the solution analysis is as follows:

Coating 1: Elements in the sample

Spectral background: Typically, the background spectrum is named with a brief designation
such as
scatt or similar. The spectrum background is included with the shipment as a file.
Other typical brief designations of the background spectrum for a FISCHER Def.MA may be streu
or wasserdummy , for example.
The Def.MA window for the Solution Analysis
There is a special Def.MA window that is particularly suited for setting up Def.MAs for the solution
analysis. The range of functions of this window is reduced to the specific functions needed for so-
lution analysis. The window is only accessible, if the SUPER software is installed.

Solution analysis .
The Def.MA dialog for the solution analysis differs from the standard Def.MA window in the fol-
lowing features:

Only the layer with the sample material (the solution to be analyzed) must be entered. Only a
maximum of one layer can be entered.

Oxygen must not be entered in the Def.MA. Oxygen is automatically taken into account when
calculating the results of the analysis. The Def.MA display window does not explicitly display
the symbol O.

Background spectra and compensation spectra are entered in the same manner as with the
typical Def.MA definition.

The material of the reference plate of the measuring cell for the solution analysis is defined
using the list field at the lower left of the window. The default setting is Mo.

The Def.MA display window does not explicitly display the material of the reference plate.
