Convenience doesn’t need to come at a cost

Convenience doesn’t need to come at a cost

Every sample introduced to an IC must be filtered, the longevity of your instrument and separation column depends on it. Historically this resulted in an expensive use of consumables. Metrohm’s Ultrafiltration Cell has changed the price of protecting your system. No more one-use filters required, the Ultrafiltration Cell makes it...

Cation suppression in ion chromatography

Improved sensitivity for trace level analysis Trace analysis of cations, amines, and transition metals is possible with or without suppression. However, if lowest detection limits and lowest preconcentration volumes are required, sequential cation suppression has its advantages. Sequential cation suppression by Metrohm is based on the proven Metrohm Suppressor Module...

Reproducibility of cation suppression

30 times 10 μg/L standard anions injected Cation chromatography with sequential suppression enables the determination of cations in their hydrogen carbonate form. The eluent – usually nitric acid – is converted into carbonic acid. Following its decomposition into carbon dioxide and water, the former is continuously removed by the CO2...
