Ion Chromatography
Shodex™ ion chromatography columns are among the best in the industry. We offer both suppressed columns for sensitive anion separations required for water analyses and non-suppressed columns that can be run on traditional HPLC systems equipped with a conductivity detector. Refer to the features for each column and the column selection guide below.

| I-524A | NI-424 provides simultaneous analysis of fluoride and phosphate ions |
| I-524A fulfills USP-NF L23 requirements |
| SI-90 4E | Suitable for anion suppressor methods with sodium carbonate eluent |
| SI-50 4E | Suitable for the quantitative analysis of fluoride ion |
| SI-52 4E | SI-50 4E separates target inorganic anions from organic acids |
| SI-52 4E provides simultaneous analysis of oxyhalides and general inorganic ions |
