2.4.4 Primary filter (Optional)
The primary filter consists of a thin foil made of nickel or aluminum, which is located
between the x-ray tube and the specimen to be measured.
By using a primary filter, the composition of the primary X-radiation can be influenced such
that it is optimally suited for the excitation of the respective specimen for x-ray fluores-
cence. Thus, undesirable components of the fluorescence spectrum can be avoided from
the outset.
Using a primary filter is useful for certain applications, however, it is not required in most
cases. The user requires special physical knowledge for a case-by-case evaluation of this
question.
The primary filter can be controlled using the software, if the WinFTM extension SUPER
is installed.
To change the primary filter:
1. In the WinFTM main window select Product > Modify… .
The window Modify product appears.
2. Select the tab Application .
3. Click Def.MA (local) .
The window Definition of measuring conditions… appears.
4. In the upper right field select the desired primary filter and click OK .
