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,
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
