Anion Standards (3) (I-524A)

Anion standards were analyzed using IC I-524A. This eluent is suitable for the separation of ions that elute before chloride. After each sample is analyzed, it is necessary to wash the column with 200 to 300micro-L of 0.1M tartaric acid when the sample contains NO₃^-, SO₄^2-, etc. because they elute very slowly and may be remaining inside the column.


Sample : 10mg/L each, 50micro-L
1. Acetic acid
2. H₂PO₄^-
3. H₂PO₂^-
4. H₂PO₃^-
5. ClO₂^-
6. BrO₃^-
7. Cl^-
