Apparatus and process for separating fluid substances.

摘要

A stationary phase (S) is distributed around the outer wall (8) of the annular channel (1) which has an inlet (2) and an outlet (3) for a mobile phase and a sample to be sepd. These are circulated (R) e.g. by pumps while the sample interacts with the stationary phase and is divided into components (A-C) having different circulation speeds. An optical detector (e.g. absorption meter or fluorimeter) (4) is sited pref. in the mouth of the inlet to detect the components after their first complete circuit.
