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