Compact module works with three suppressor units in a rotor - one suppressor unit is always in use, while the two others are regenerated and rinsed respectively
Ion chromatography with Metrohm keeps two paths open: measurements with electronic suppression and measurements with chemical suppression.
For measurements with electronic suppression the outstanding electronic properties of the Metrohm detector are utilised.
These properties are also effective for measurements at low background conductivities after chemical suppression.
The MSM Metrohm Suppressor Module is specially designed for the analysis of anions; suppression only achieves increased sensitivity in anion analysis.
The MSM can also be used for sample preparation.
For example, it is able to neutralise concentrated bases or to eliminate heavy metals from the sample. It can also be combined with any other IC or HPLC system.
The compact MSM Metrohm Suppressor Module works with three suppressor units in a rotor.
One suppressor unit is always in use, while the two others are regenerated and rinsed respectively.
In this way each chromatogram - with excellent reproducibility - is recorded with a freshly regenerated suppressor.
The individual suppressors cannot be distinguished from each other in the analysis.
The IC Suppressor Module consists of two units: the two-channel peristaltic pump for supplying dilute sulfuric acid and water for regenerating and rinsing the suppressor, and the suppressor itself which, for example, is installed in the 733 IC Separation Centre.
The MSM is pressure-resistant up to 2MPa.
Higher pressures separate the two ceramic valve disks of the MSM and leakage occurs.
Work can be continued as soon as the pressure returns to normal values - the MSM again functions properly.
The mature concept of the MSM allows the use of organic solvent fractions in the eluents - the MSM is 100% solvent-compatible - in order to optimise the separation or to prevent bacterial growth in the eluent.
Metrohm offers ten years' warranty for IC suppressors sold in 2003.
