... of the separating resin. Ligands are also required to avoid precipitation when an acidic eluent is not suitable for the columns selected. A low-capacity silica-based cation-exchange column was used for the separation of transition metals (Co, Cu, Fe) and coupled with post-column chemiluminescence de ...
