Metrohm has published a brochure summarising the theoreretical aspects and practical benefits of suppression in ion chromatography.
Suppression plays a key role in ion-exchange chromatography and conductivity detection.
It is widely used, for example, for the analysis of anions and organic acids.
As a practical solution for ion chromatography suppression decreases the background conductivity of the eluent, minimises baseline noise, optimises the signal-to-noise ratio and increases the sensitivity of the measuring system.
The Metrohm Suppressor Module (MSM) is claimed to be the most efficient and robust technical solution to implement suppression in ion chromatography.
The patented MSM consists of a small rotor containing three cartridges filled with cation exchanger resin.
While the first cartridge is used for suppression, a regeneration step is performed on the second cartdrige. The third cartridge is rinsed automatically during this time.
Hence, with each shifting of the rotor, a freshly regenerated suppressor cartridge is always available for every new sample.
Product features:
- Measurements can be started half an hour after switching the IC system on.
- Applications can be changed at any time with no impact on system performance.
- The MSM comes with a 10 year warranty.
