Metrohm inline calibration permits very low concentrations – in the ppt range (ng/L) – to be reliably calibrated using a single standard of higher concentration – in the ppb range (µg/L).
The sample is transferred to the preconcentration column fully automatically and with high precision by the intelligent 800 Dosino. 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 bases. The matrix is then removed from the preconcentration column in a rinsing step. The clean and pH-neutral sample is then injected to the IC system.
The 850 Professional IC – Prep 3 is equipped with a sample preparation module. Sample and rinsing solution are delivered by the 800 Dosino. A valve on the 858 Professional Sample Processor switches sampling and sample transfer. The 872 Extension Module is used for inline calibration. The intelligent MagIC Net™ software controls and monitors the system.
Calibration and calculation of the results as a function of preconcentration volume are provided by the MagIC Net™ software. Different sample volumes can be conveniently entered in the sample table. Even if complex procedures are involved, operating the system is perfectly easy.
«ProfIC 11» features intelligent system components such as the iPump and the iDetector and provides space for a total of three iColumns. The system is equipped with sequential suppression.
The 858 Professional Sample Processor – Pump – Injector provides for sample delivery. Numerous sample racks for volumes 0.5...500 mL are available.
