"ProfIC 7 – Anion" – Professional IC System with Inline Dilution and Dialysis

The professional IC system with conductivity detection enables the fully automatic determination of anions that are present in very high concentrations and in a problematic matrix. Emulsions, samples containing fats and proteins or heavily contaminated waste waters are not always compatible with ion chromatography, even after upstream filtration. That is why "ProfIC 7" is equipped with the Metrohm-patented Inline Dialysis (European Patent 0 820 804, US Patent 5,861,097).

Thus it is possible to determine anions, even in cutting oil emulsions, milk products or bodily fluids such as blood and urine.

"ProfIC 7" offers in addition the option of automatic inline dilution of the sample. This takes place at an external position on the 858 Professional Sample Processor. Working together with a transfer tubing, the 800 Dosino performs the Liquid Handling in a highly precise manner.

The intelligent MagIC Net™ software controls both the dialysis and also the dilution steps. MagIC Net™ carries out all the calculations, so that only the dilution factor needs to be entered. In addition, the software offers the option of intelligent dilution, i.e. the dilution takes place automatically, depending on the highest concentration of the calibration. The software monitors the results and makes logical decisions.

The anion system is equipped with sequential suppression. Very high sensitivity is achieved with the unique combination of chemical and downstream CO ₂ suppression. This makes it possible to combine the flexibility of the carbonate/hydrogen carbonate eluents with the low background conductivity of a hydroxide eluent.

The 858 Professional Sample Processor with pump takes care of the sample transfer. Numerous sample racks are available for volumes in the range of 0.5 - 500 mL.
