Please use this column with suppressor type ion chromatography system. Perchloric acid was analyzed by an ion chromatography column (anion), SI-90 4E. Since perchloric acid is a highly hydrophobic ion, addition of acetonitrile in the eluent shortens the retention time. Sample : 100μL 1. Cl- 3mg/L 2. NO3- 10mg/L 3. SO42- 15mg/L 4. ClO4- 10mg/L
Column : Shodex IC SI-90 4E (4.0mmI.D. x 250mm)
Eluent : 6mM Na2CO3 aq. + 10% CH3CN
Flow rate : 1.0mL/min
Detector : Suppressed conductivity
Column temp. : 25°C
