Abstract: A valve may be utilized in a high-performance chromatography system for separating components of a sample liquid introduced into a mobile phase. The valve has a first valve element and a second valve element. By a movement of one valve element relative to the other, a first effective surface of the first valve element is brought into connection with a second effective surface of the second valve element, and a flow path may be produced or suppressed. The second valve element has an elastic region to compensate for an axial angle between the first valve element and the second valve element, such that the first effective surface and the second effective surface may be oriented parallel to each other. This may favorably influence a fluidic leak tightness and/or longevity of the valve.

Abstract: 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.
