Gradient Techniques in Cation-Exchange Chromatography of Inorganic and Organic Cations 

20 mg/L tetraethylenepentamine. lonPac CS3 is no longer available, but can be replaced by lonPac CS10 (4 mm) or lonPac CS11 (2 mm). 

The separation of ethylamines together with the standard cations can also be performed in a simple way with a linear acid gradient by exploiting the selectivity change caused by the crown ether functional groups of lonPac CS15. To
