Please use this column with suppressor type ion chromatography system.
Anions in sea water were analyzed by anion-chromatography column, IC SI-90 4E Compared to chloride which is highly concentrated in sea water, concentration of nitrous acid is too low, and thus interfered by chloride ion peak to be monitored by a CD. Since nitrous, bromine, and nitrate ions have UV absorbance, they can be monitored by UV detector without being affected by chloride ion.
