Abstract
A fluidic valve includes a valve seat, a valve sealing body placeable at the valve seat when the fluidic valve is closed and being displaced with respect to the valve seat when the fluidic valve is open, a force transmission element coupled with the valve sealing body, and an actuator mechanism configured for actuating the force transmission element for triggering the valve sealing body to carry out an additional movement different from an opening movement and a closing movement of the valve sealing body.
Claims18
A fluidic valve, comprising:
- a valve seat;
- a valve sealing body placeable at the valve seat when the fluidic valve is closed and being displaced with respect to the valve seat when the fluidic valve is open;
- a force transmission element coupled with the valve sealing body;
- an actuator mechanism configured for actuating the force transmission element for triggering the valve sealing body to carry out an additional movement different from an opening movement and a closing movement of the valve sealing body;
- and
- a membrane including at least part of the actuator mechanism.
A sample separation apparatus for separating a fluidic sample, the sample separation apparatus comprising:
- a fluid drive for driving the fluidic sample and/or a mobile phase in which the fluidic sample is injected;
- a sample separation unit for separating the fluidic sample in the mobile phase;
- and
- a fluidic valve comprising:
- a valve seat;
- a valve sealing body placeable at the valve seat when the fluidic valve is closed and being displaced with respect to the valve seat when the fluidic valve is open;
- a force transmission element coupled with the valve sealing body;
- and
- an actuator mechanism configured for actuating the force transmission element for triggering the valve sealing body to carry out an additional movement different from an opening movement and a closing movement of the valve sealing body.

- a membrane including at least part of the actuator mechanism;
- a sensor mechanism configured for sensing a response to the triggered reference movement;
- and
- a determining unit configured for determining information indicative of at least one parameter relating to an operation of the fluidic valve.
