# QA Mode

**QA mode** allows the user to check the conformity of selected materials with a chemical composition  typically measured by a spectrometer. Between 1 and 5 materials (maximum) can be added for conformity checking within the QA mode.

This mode should be used when the user wants to understand if the composition of a material matches an expected and predefined specification, one typical example being inspection and control of incoming materials delivered by an external supplier.

In the result list, materials will be shown with their calculated similarity. You can see the details on the right side.

In QA mode, the user can apply similar filtering options as in Expert mode to achieve more precise results.
