Anion Standards (1) (I-524A)

Anion standards were analyzed using IC I-524A. A phthalic acid eluent is recommended for the general analysis. Most of the important anions such as F^–or H₂PO₄^–, Cl^–, NO₂^–, Br^–, NO₃^– and SO₄^2- can be analyzed with this eluent. Therefore, it is suitable for the routine alysis of anions.

Sample :

1. H₂PO₄^– 30mg/L

2. Cl^– 5mg/L

3. NO₂^– 10mg/L

4. Br^– 10mg/L

5. NO₃^– 10mg/L

6. SO₄^2- 10mg/L
