The present invention provides an apparatus for discharging packing material from a sample column which is capable of removing the packing material such as activated carbon from the sample column for analysis having a tube shape smoothly and more certainly, and can be suitably used in the case where the packing material thus removed is supplied to an analyzer, etc. The apparatus for discharging packing material according to the present invention comprises a discharge apparatus body (4) which is disposed concentrically to the sample column (9) held in a predetermined position, and is capable of moving close to and away from the sample column; a column positioning hub (5) which is mounted to a tip end of the discharge apparatus body to be movable forward and rearward, and biased toward the sample column (9); a push-out pin which is inserted into the discharge apparatus body (4) and the column positioning hub (5) to extend substantially along center lines of the discharge apparatus body and the column positioning hub, and allowed to relatively project from the column positioning hub when the column positioning hub (5) is moved rearward; and a vibration generating means for applying vibration to the push-out pin (6) when the push-out pin is allowed project from the column positioning hub.
