3. Theory about Ion Chromatography

There are two types of Ion Chromatography methods: The suppressor method and non-suppressor method.

 

Shodex carries columns suitable for both types. As the name tells, the suppressor method uses a suppressor which removes ions that interfere with analytes measurement. The suppressor system is expensive, but some say the sensitivity of suppressor method is superior to non-suppressor method. In contrast, system required for non-suppressor method is cheaper, but the useable solvent is limited to the ones with low conductivity such as phthalic acid.

Suppressor Type Ion Chromatography Column
Shodex IC SI-90 and SI-50 are the suppressor type anion chromatography columns. SI-50 is the higher performance type of SI-90. SI-52 is another suppressor type column suitable for the separation of oxyhalides.

Non-Suppressor Type Ion Chromatography Column
Shodex IC I-524A and NI-424 are the non-suppressor type anion chromatography columns. NI-424 is the higher performance type of I-524A.

Shodex IC YK-421 and YS-50 are the non-suppressor type cation chromatography columns. YS-50 is the higher performance type of YK-421. They can separate both monovalent and divarent cations simultaneously.
