Shodex: Packed Columns for HPLC Analysis

Ion Chromatography Columns

There are two types of ion chromatography: non-suppressor method and suppressor method. While the suppressor method requires a suppressing module, the non-suppressor method can be used for ion analysis by simply connecting an electro-conductivity detector to an all-purpose LC system. At Shodex, we provide columns for cation/anion analysis for both non-suppressor and suppressor methods. We also provide columns for analyzing transition metal ions and rare earth metal ions using the post-column reaction system. Column selection can thus be made based on your analysis needs and type of ions.

IC NI-424 IC I-524A	These columns are for anion analysis using the non-suppressor method. NI-424 is a high performance version of I-524A and can analyze fluoride ion and phosphoric acid simultaneously which was not possible with I-524A.
IC Y-521 IC YK-421	These columns are for cation analysis using the non-suppressor method. Y-521 is suitable for the separation of various alkylamines. YK-421 can be used for simultaneous analysis of monovalent and divalent cations.
IC SI-90 4E IC SI-50 4E IC SI-52 4E New IC SI-91 4C	These columns are for anion analysis using the suppressor method. They demonstrate good performance in fluoride ion assays, separation/removal of foreign organic acids and are not affected by carbonate system peaks. They are thus suitable for anion analysis of various samples. They can be used with ion chromatography systems equipped with a suppressor.
IC T-521 IC R-621	T-521 is for analyzing transition metal ions and R-621 is for analyzing rare earth metal ions. The high sensitivity of metal ions in the post column reaction system can be used for measurement.
