Effects of Temperature on Retention Time (SI-35 4D)

Please use this column with suppressor type ion chromatography system.

Shodex IC SI-35 4D (a column for rapid oxyhalides analysis) was used to analyze several anions and oxyhalides. Similar to SI-52 4E, SI-35 4D' s elution time of some oxyhalides is dependent on column temperature. For a best separation of (Br-) and chlorate (ClO3-), column temperature of 45 °C is recommended.
