A small volume of the sample is transferred fully automatically to the preconcentration column. On its way it passes through the sample preparation module, where complete cation exchange takes place. This means that it is possible to neutralize both acids and alkalis. The matrix is then removed from the preconcentration column in a rinsing step and the clean and pH-neutral sample injected to the IC system.
For liquid handling the 858 Professional Sample Processor – Pump – Injector is equipped with an additional valve. An additional peristaltic pump transfers the sample and rinsing solutions. The intelligent MagIC Net™ software controls and monitors the system.
«ProfIC 10» is equipped with sequential suppression. Very high sensitivity is achieved by this unique combination of chemical and downstream CO2 suppression. 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.
«ProfIC 10» features intelligent system components such as the iPump and the iDetector and provides space for a total of three iColumns.
The 858 Professional Sample Processor – Pump – Injector is responsible 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 and neutralization.
