Effects of Added Acetonitrile on the Retention Time (SI-90 4E)
Please use this column with suppressor type ion chromatography system.
Ion chromatography column, IC SI-90 4E, was used for the quantification of several anions.
Addition of acetonitrile to the eluent will decrease the retention time for the elution of I– and SCN– ions.
