HIC-ESP Anion Chromatograph Equipped with the ICDS™-40A High-Performance Suppressor

In ion chromatography, the suppressor method is widely used in order to reduce background and noise levels during detection. The newly developed ICDS-40A electrodialytic suppressor for anion analysis features (1) a dialytic membrane suppressor with a folded structure that reduces the internal volume and inhibits peak dispersion (2) a continuous regeneration method that shortens the analysis cycle time, and (3) a simple system configuration, based on electrodialytic regeneration, that eliminates the need for a regeneration solution. The HIC-ESP anion chromatograph equipped with the ICDS-40A suppressor features a slim oven, which reduces the installation width by 40 % to help utilize laboratory space more effectively.
This Technical Report bulletin describes the operating principles and features of the ICDS-40A suppressor and the HIC-ESP anion chromatograph.
