Chromatographic determination boundary conditions

Each column in Figure 1R-14B acts as a chromatographic column that undergoes a series of steps. The solute velocity in each column of the SMB can be determined in the same way as for an elution chromatography system Thus, the solute velocity in any column of the SMB is given by Eqs. flS-lST The chromatography and SMB processes differ only in the way columns are coupled, which are their boundary conditions ...
