Rapid Analysis of Oxyhalides and Anions (SI-35 4D) (1)

Please use this column with suppressor type ion chromatography system.

The analytical performance of Shodex IC SI-35 4D (a column for rapid oxyhalides analysis) was compared to the existing oxyhalides-analysis column, SI-52 4E. The analysis time required by SI-35 4D is only one half of SI-52 4E 's analysis time.


Sample : (SI-35 4D) 20 μL, (SI-52 4E) 50 μL
1. F- 2 mg/L
2. ClO2- 1 mg/L
3. BrO3- 1 mg/L
4. Cl- 10 mg/L
