摘要：
Axial compression of the stationary phase is an easy technique for packing preparative liquid chromatography columns. However, the compression piston often needs an important external device to move the external jack. A new type of column is described which uses an auto-compression system to move the piston and compress the packing material. The system is fitted with a new annular injector which is known to reduce the peak tailing. The results of the tests demonstrate the ease of use of this column, its efficiency and stability.
