IC processor incorporates ultrafiltration

The 788 IC filtration sample processor from Metrohm integrates membrane filtration as a sample preparation step directly into the IC system. Equipped with an ultrafiltration cell, it combines in-line filtration with automatic sample application.

The samples are placed directly on the turntable and are then processed automatically by the IC filtration sample processor. The sample solution to be filtered passes through a membrane and the filtrate is aspirated off the rear of the membrane, transferred to the sample injection valve of the chromatograph and injected.

The membrane may be used for many or just a few samples, depending on the sample matrix, the pore size and properties of the membrane.
