«ProfIC 3» festures intelligent system components such as the iPump and the iDetector and provides space for a total of three iColumns.
The Professional IC system «ProfIC 3» is equipped with «Inline Stopped Flow Dialysis», which has been patented by Metrohm (European Patent 0 820 804, US-Patent 5,861,097). This fully automatic sample preparation technique effectively removes particles and colloids from the samples to be analyzed. Emulsions, samples containing fats and proteins, body fluids and strongly polluted wastewater can be reliably determined without damaging the analytical column. The driving force behind dialysis is diffusion. This means that only the ions and not the particles can pass through the dialysis membrane. This extends the lifetime of the membrane and, for example, prevents oil droplets from reaching the analytical column through the membrane, as would be the case if filtration was to be used.
The dialysis cell is mounted directly in the 850 Professional IC. The interplay between the two bidirectional peristaltic pumps at the 858 Professional Sample Processor – Pump and 850 Professional IC – Prep 1 allows the dialysis to be controlled by MagIC Net™.
Numerous sample racks for volumes 0.5...500 mL are available for the 858 Professional Sample Processor. Dialysis requires at least 10 mL of the sample.
