Separchrom PC01 ECOM columns correspond to the highest requirements of preparative liquid chromatography. They are designed to be used in a mode of axial compression with a moving input piston. In the original design, they are equipped with identical pistons on input and output (biaxial compression as an option). In the ECOM Separchrom PC FE modification, they have a fixed end plate on the output instead of the piston. Pistons and plates are equipped with frits. A liquid distributing system is installed under each frit. The design guarantees perfect piston flow, high efficiency even for high injection volume, and simple accessibility of frits for cleaning. Columns can be packed by dynamic slurry method or by sedimentation or with sorbent in a dry state.
