Effect of Methanesulfonic Acid Concentration on Elution Time (YS-50)

Using IC YS-50, changing the concentrationt of methanesulfonic acid in the eluent enables to control cations separation and retetntion time. Although, retention time of cations will become short if concentration is high, the eluent conductivity (background level) becomes also high.
