Abstract
A micro column system is provided for high gradient magnetic field separation of macromolecules and/or cells. The system provides fast kinetics and high efficiency as well as the purity and simplicity of a column separation. A yoke provides a magnetic field to a plurality of micro columns. A separation and release process for purifying biological material on the column includes release of the biological material from magnetic particles and elution from the column while the magnetic particles are still magnetically retained by the matrix inside the column.
