Monovalent and Divalent Cation Standards (Eluent Containing Acetonitrile)

Shodex has investigated the differences between Monovalent and Divalent Cation Standards using IC YS-50 column and eluent containing Acetonitrile. IC YS-50 can use the eluent adding acetonitrile (up to 50%). Adding acetonitrile can weaken hydrophobic interaction, and therefore quicken the elution of highly hydrophobic cations.
