Abstract
A method of performing foam separation utilizes a gas-liquid dual countercurrent flow through a helical column subjected to a particular type of synchronous planetary motion. Samples introduced at the middle portion of the column, either continuously or batch wise, are separated according to the foam affinity. Any material having an affinity to the foam is quickly carried with the foaming stream and eluted through one end of the column, whereas other materials are carried with the liquid stream in the opposite direction and eluted out through the other end of the column.
