 note = {Article, Simultaneous chromatographic separation of nitrate ion (NO_3^−), nitrite ion (NO_2^−) and ammonium ion (NH_4^+) was obtained using single injection, single column and a detector (conductivity). The principle is based on selective ion-exclusion effect for NH_4^+ and anion-exchange effects for NO_3^− and NO_2^− on an OH^−-formed basic anion-exchange resin column (Tosoh TSKgel Super IC-AZ) with basic eluent (2 mol/m^3 KOH). The present system could determine NH_4^+, NO_2^− and NO3− in 500-fold diluted artificial seawater sample in 40 min at 0.6 mL/min of flow rate, by standard addition method. Also, this method was applicable to nitrogen analysis in artificial seawater with iron matrix, by pre-column packed with an iminodiacetate chelating resin in order to remove iron or calcium ions.},
