Verfahren und Einrichtung zur Trennung eines Hauptmediums von einem Strom, der durch einzelne Abschnitte des Hauptmediums und eines Trennmediums gebildet wird

摘要

Segmented main fluid in a capillary stream is allowed to flow through a main tubing equipped with a capillary slot communicating with an offtake pipe. Conditions within the apparatus are maintained such that capillary forces and surface tension inherent in the elements of the segmentation medium and other parts of the system prevent their passage through the capillary slot, through which the main fluid only is taken off in a continuous stream. The length of the capillary slot in the direction of the main capillary tubing axis exceeds the maximum contact length of a segmentation medium element; the main fluid may be taken off substantially from a single one only, or from not more than two neighboring segments of the main medium, so that contamination by the contents of other segments is negligible.
