ABSTRACT:
A sampling probe for sampling partial quantities of liquid in a counter-current extraction column wherein the liquid has first and second immiscible phases moving in mutually opposite directions. The probe comprises an extraction tube having first and second radially opposing ports in its surface, the extraction tube being adapted for extending into the liquid within the column and positioned so that the first and second phases impinge upon the respective opposite portions of the extraction tube surface containing the radially opposing ports. A stopper formed of a material which promotes coalescence with respect to the first phase is fitted into one end of the extraction tube. The stopper has a cavity therein, and a plurality of apertures are located in the side of the stopper aligned with the portion of the extraction tube against which the first phase impinges. A conical valve formed of a material having substantially the same coalescing properties as the stopper material is slidably positioned within the extraction tube between the stopper and the other end of the tube. Channels located within the valve connect the cavity in the stopper with the interior of the extraction tube.
