Abstract
Particulate chromatography medium such as silica is packed into a chromatography column ( ) along a feed conduit ( ) leading to a packing port ( ) through the column wall. A motive flow of a liquid packing vehicle such as a non-polar organic solvent is established along a feed conduit by a pump ( ). The medium, for example silica which is poorly compatible with low-polarity vehicles, is easily entrained in the motive flow by introducing it into the feed conduit ( ) via an ejector ( ). This avoids subjecting the medium to the action of a mechanical pump.
