Analysis of Hydrophobic Anions (I-524A)

Print

Four hydrophobic anions were analyzed using an anion analysis column for non-suppressor method, IC I-524A. The method optimized here is able to analyze hydrophobic anions without the interference of standard anions.


Sample : 20μL
1. Cl- 5mg/L
2. NO3- 10mg/L
3. SO42- 10mg/L
4. S2O32- 50mg/L
5. I- 50mg/L
6. SCN- 50mg/L
7. ClO4- 50mg/L
