MICRO-FLUIDIC DEVICE WITH DEGAS CONTROL

摘要

An arrangement of a micro-fluidic device and a controller according to a first aspect of the present invention comprises a microfluidic device which comprises at least one micro-fluidic channel for holding a fluid. The micro-fluidic channel has an interior channel wall, at least part of the interior channel wall being made from semi- permeable material. The micro-fluidic device comprises a plurality of electrodes present at the interior channel wall. The controller is adapted for measuring the value of an electrical property of the fluid between at least two electrodes of the plurality of electrodes and for generating an output signal dependent on the measured value of the electrical property indicating whether a gas volume is present between the at least two electrodes.
