Effects of Column Temperature on Retention Time (SI-50 4E)
Please use this column with suppressor type ion chromatography system.
IC SI-50 4E is
suitable for anion and organic acid analysis. The temperature dependency
of retention time is observed: At higher temperatures, elution time of
anions that elute later than phosphate (PO43-) tend to be longer and that of anions elute before nitrate (NO3–) tend to be shorter.
