AI summary
In a method for characterizing a property of a flow path, in particular of an element in the flow path, in an analysis device, the volume of a fluid in the flow path, in particular in the element of the flow path, is changed in order to change the pressure in the flow path. The pressure change in the flow path as a consequence of the volume change is determined. The property of the flow path is characterized based on the determined pressure change and/or the volume change.
