Abstract (en)
[origin: EP2308597A2] The channel (10) has an end, and a gas and liquid permeable wall section arranged at the end of the channel, where the wall section provides a gas conduit (27). The channel is connected with a fluid pipeline at another end of the channel. A separating unit e.g. rotary valve, is arranged at the latter end, and a defined liquid volume is enclosed between the wall section and the separating unit in the channel. The gas and liquid permeable wall section is designed in the form of a membrane (26). The channel is closed or closeable on the former end. Independent claims are also included for the following: (1) a microfluidic structure in a substrate, comprising a measurement channel (2) a method for measuring and/or positioning volume of liquid in a microfluidic system.
