ProfIC Vario 5 Anion is a Professional IC Vario system with variable sample preconcentration for trace analysis of anions and cations with sequential suppression. With the ProfIC Vario 5, concentrations down to the ppb range (μg/L) can be reliably determined. The intelligent 800 Dosino carries out the high-precision sample preconcentration on the preconcentration column, thus dispensing with the sample loop.
