This means that it is possible to preconcentrate and analyze more than 50 mL of the sample instead of the 10...20 µL sample used for direct injection via the sample loop. It is also possible to calibrate the system using the 800 Dosino. In this case it will do to work with the single most concentrated standard, from which varying volumes are transferred to the preconcentration column. This opens the single digit ppb range even for routine analysis.
«ProfIC 5» features intelligent system components such as the iPump, the iDetector and the 800 Dosino and provides space for a total of three iColumns. The MagIC Net™ software monitors and controls the functions of all components.
The anion system is equipped with sequential suppression. This unique combination of chemical and downstream CO2 suppression allows the achievement of 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 supplies the samples. Transfer is carried out by the 800 Dosino. Numerous sample racks are available for volumes 0.5...500 mL. The minimum volume for preconcentration is 0.5 mL.
