Claim 1:
2. A method for operating a cartridge that comprises an inlet port and an internal gap with a capture zone and a transfer zone, the method comprising:
providing an input liquid that comprises a processing liquid and a carrier liquid and the providing of the input liquid is accomplished by alternatingly feeding the processing liquid and the carrier liquid into the inlet port before entering the internal gap;
capturing a part of the processing liquid in the capture zone by use of electrowetting force;
transferring the carrier liquid from the inlet port to the internal gap via the transfer zone, while the part of the processing liquid is captured in the capture zone; and
using the part of the processing liquid in the capture zone for providing a microfluidic droplet that is movable by applying an electrowetting force to the microfluidic droplet.
