Shimadzu HIC-ESP anion suppressor ion chromatography system

Shimadzu’s HIC-ESP, an anion suppressor ion chromatograph with a built-in electrodialytic suppressor, features the same low carryover and injection precision characteristic of the company’s HPLCs. The system is suitable for applications in a wide range of fields including environmental science, medicine, chemistry and food science.

The product’s ICD-40A anion suppressor unit achieves high efficiency and stable suppressing while maintaining a small internal volume, due to an eluent flow path that bends back around and an optimised dialytic. The unit reduces peak spreading — increasing the sensitivity for components with low retention such as fluorine ions — and improves water dip separation, providing stable functionality even over long periods of use.

Using an electrodialytic system that can carry out analysis and regenerations simultaneously, the analysis cycle time can be reduced and consecutive regeneration achieved, increasing the flexibility of the analysis time settings. In addition, the suppressor uses waste solution from the detector as regenerating solution, making environmentally unfriendly regenerating solutions such as sulfuric acid unnecessary.
