Abstract

PURPOSE: To automatically measure only the ammonium ions rapidly with high sensitivity by letting an aqueous sample solution be adsorbed in the column which has been packed with hydroxide type strong basic anion exchange resins, letting only the ammonium hydroxide elute by water and measuring the same by a flow type detector.
CONSTITUTION: A fixed amount of the aqueous sample solution containing ammonium ions is pressure-injected to the upper part of the column which has been packed with hydroxide type strong basic anion exchange resins, whereby it is adsorbed in the resins. Thence, pure water or the mixed solution of pure water and organic solvent is automatically and continuously pressure-injected at a fixed flow rate, so that only the ammonium hydroxide is automatically separated and eluted from the lower part of the column. Next, the ammonium ions in the eluate are detected by using a conductivity detecting method and flow coulometry method respectively independently or the both thereof, and the ammonium ions are automatically measured from the areas or heights of the peaks of the chromatograph thus obtained.
