Abstract
A method of evacuating a liquid sample from an open port interface (OPI) via a pressure drop includes applying the pressure drop to a transport liquid. This application generates a plurality of bubbles in the transport liquid during evacuation of the transport liquid from the OPI via a transfer conduit. The liquid sample is separated from a subsequent liquid sample by at least one of the generated bubbles.
