Anion Standards (3) (I-524A)

Anion standards were analyzed using IC
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,
SO42-, etc. because they elute very slowly and may
be remaining inside the column.

Sample : 10mg/L each, 50µL

1. Acetic acid

2. H2PO4

3. H2PO2

4. H2PO3

5. ClO2

6. BrO3

7. Cl
