Effect of flow rate on column efficiency when IC SI-90 4E (a column for anions analysis) is used for the analysis of anions is shown here.
Sample : Cl–
Column : Shodex IC SI-90 4E (4.0mmID*250mm)
Eluent : 12.0mM NaHCO3 aq.
Flow rate : 1.0 to 2.0mL/min
Detector : Shodex CD-5 and Suppressor module
Column temp. : 25°C
