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.

| 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. |
|
| These columns are for cation analysis using the non-suppressor method. Y-521 is suitable for the separation of various alkylamines. YK-421 and YS-50 can be used for simultaneous analysis of monovalent and divalent cations. YS-50 is a high performance version of YK-421. |

| 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. |
|
| 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. |
