The quantitative performancefor NH 4+ in a sample containing highconcentration Na + is also enhanced.Resolutionfactor ofNa + and NH 4+YS-502.5YK-4212.1Standard AnalysisColumns018-Crown 6-ether conc.6mM3mM1mM0mM5 10 15 20 min 0 5 10 15 20 minColumn : Shodex IC YS-50Eluent : 4mM Methanesulfonic acid aq.Flow rate : 1.0mL/minDetector : Non-suppressed conductivityColumn temp. : 40˚CEffects of crown ether in eluentCrown ether forms complex with cations. The elution ofcations (particularly K + ) can be well controlled by thedifference in complex formation rate.1221 321 33213444545556666Sample : 10μL1. Li + 2mg/L2. Na + 10mg/L3. NH + 4 10mg/L4.
