If your instrument is equipped with a changeable collimator the pure element spectrum can
automatically be measured for all collimator sizes by activating the respective radio button.
These steps have to be followed to perform a measurement of a pure element spectrum:
1. Select
the
Elements
tab.
2. Select the measurement parameters (Pure element spectra can be recorded for different
preset conditions such as tube voltage and current).
3. Choose whether the pure element spectrum is to be recorded for all collimators automatically
or only for the currently set one.
4. Click on the
icon and select an element (Elements already measured for the preset
conditions are highlighted).
5. Put in and align the respective pure element sample.
6. Start the measurement with

5.4.3 Measuring Primary Spectra
The primary spectrum is used as a measure for the excitation intensity of a sample under the
preset tube parameters. In order to get reliable quantitative results, very good counting statistics is
needed for these reference measurements.
If the instrument is equipped with a changeable collimator, the primary spectrum can automatically
be measured for all collimator sizes by activating the respective radio button.
