Professional IC system for the determination of anions in difficult matrices. «ProfIC 8» with Metrohm inline sample preconcentration and matrix elimination allows chromatography unaffected by matrix influences and guarantees that the analytical column has a long lifetime.
A small volume of the sample is transferred fully automatically to the preconcentration column. The anions are retained. The matrix can be removed in a rinsing step. The clean sample is then injected to the IC system.
The 850 Professional IC – Prep 2 is equipped with an additional valve for liquid handling. The peristaltic pump transfers the sample and the rinsing solutions. The intelligent MagIC Net™ software controls and monitors the system.
The anion system is equipped with sequential suppression. This unique combination of chemical and downstream CO2 suppression results in very low detection limits. The flexibility of the carbonate eluent is complemented by the low background conductivity of a hydroxide eluent. With the preconcentration technique carbonate interference is practically eliminated.
The 858 Professional Sample Processor provides for sample delivery. Numerous sample racks for volumes 0.5...500 mL are available. Only small sample volumes of about 1 mL are normally required for matrix elimination.
