A method of ion-exchange chromatography with direct conductivity detection to determine three homologous quaternary ammonium cations( tetramethyl-ammonium cation,tetraethyl-ammonium cation and tetrapropyl-ammonium cation) was developed. Three homologous quaternary ammonium cations were separated on a sulfonic acid base cation-exchange column using ethylenediamine- citric acid- acetonitrile as eluent. Effects of eluent types,eluent concentrations and column temperatures on retention and… CONTINUE READING
