(1) Enables the separation of H2PO4- and F- which were dif■cult to separate with I-524A.(2) Provides sharper peaks, and resolution between all peaks are well de■ned. Especially, the separation of Cl- and NO2- is improved.SI-52 4E is a high resolution column offering 14,000 or higher theoretical plate number. It supports simultaneous analysis of oxyhalides and inorganic anions. It is recommended to set the column temperature at 45 ºC.Sample : 50 L 1. F- - 2. ClO2- 3. BrO3 4. Cl- - 5. NO2 6. Br- - 7.
