ProfIC Vario 9 – AnCat is a Professional IC Vario system with variable sample preconcentration and Matrix Elimination for trace analysis of anions and cations. With the «ProfIC Vario 9», concentrations down to the sub-ppb range (μg/L) can reliably be determined. The intelligent 800 Dosino carries out the high-precision sample preconcentration on the preconcentration columns, which replace the sample loops and removes the sample matrix using the Matrix Elimination technique.
