Sea Water (1) (I-524A)

Anions in sea water were analyzed using IC I-524A. Since sea water contains a considerable amount of chloride ion, the chlorine should be removed prior to analysis. Put Ag-type cation exchanger in a disposable syringe and pass the sea water through the syringe. After the pretreatment, other anions can be analyzed without the interference from chloride ion.
