Automated Material Identification (Class of Materials) Features of WinFTM BASIC and LIGHT
2.6 Automated Material Identification (Class of Materials)
You can easily sort specimens with different compositions and/or coating thicknesses in
different classes of materials. You don’t need to perform reference measurements for
each composition or coating thickness. Each class of materials covers a range of compo-
sition and/or coating thickness.
Example: You need to sort the following specimens:

5 – 8 μ m Zn/Fe

10 – 20 μ m Zn/Fe

5 – 12 μ m NiZn/Fe
In WinFTM you define three classes of materials, perform one measurement and WinFTM
displays, what class of materials the specimen belongs to.
Additionally, you can assign a product to each class of materials. The exact composition
is measured. This has the following advantages:

The right product containing the appropriate parameters and calibration is loaded auto-
matically.

Measurement errors, caused by wrong product selection, are avoided.
2.7 Measurement Methods

Measurement by x-ray emission

Measurement by x-ray absorption

Measurement by simultaneous x-ray emission and x-ray absorption (Ratio Method)

Mathematical deconvolution

Measurement by Fundamental Parameter Method
The measurement methods comply with the following standards:
