Ion chromatograph IC6000

How does ion chromatography work?

The working process of the ion chromatograph is: the infusion pump delivers the mobile phase to the analysis system at a stable flow rate (or pressure), introduces the sample through the sampler before the chromatographic column, and the mobile phase brings the sample into the chromatographic column. The components in the medium are separated and flowed to the detector in turn with the mobile phase. In the suppressed ion chromatography, a suppression system is added before the conductivity detector, that is, another high-pressure infusion pump is used to deliver the regenerated fluid to the suppressor. In the process, the background conductivity of the mobile phase is reduced, and then the effluent is introduced into the conductivity detection cell, and the detected signal is sent to the data system for recording, processing or storage. The non-suppressed ion chromatograph does not need a suppressor and a high-pressure pump to transport the regenerant, so the structure of the instrument is relatively simple.
