Monovalent and divalent cation standards were analyzed using IC YK-421. The effect of the acetonitrile concentration in 3 mM nitric acid on elution volume of cations is shown. By increasing the acetonitrile concentration, the cations are eluted faster. Especially, the elution volume of divalent cations are eluted faster markedly. When the acetonitrile concentration of acetonitrile is higher than 50 %, to the contrary, cations are eluted slower a little by increasing acetonitrile concentration.
