A small sample volume is transferred to the preconcentration column fully automatically. In doing so, the sample passes the sample preparation module. A nearly complete cation exchange takes place here. Thus it is possible to neutralize not only caustics but also acids. Afterwards, the matrix is removed from the preconcentration column in a rinsing step. It is only now that the pH-neutral and matrix-free sample is passed along into the IC system. It is through the neutralization of the sample that the preconcentration becomes possible at all.
The 858 Professional Sample Processor – Pump – Injector is equipped with an additional valve for Liquid Handling. An additional peristaltic pump takes over the transfer of the sample and the cleaning solution. The control and monitoring of the system takes place through the intelligent MagIC Net™ software.
"ProfIC 10" is equipped with sequential suppression. Very high sensitivity is achieved with the unique combination of chemical and downstream CO
2 suppression. This makes it possible to combine the flexibility of the carbonate/hydrogen carbonate eluents with the low background conductivity of a hydroxide eluent. The disruptive carbonate influence can be greatly reduced in the preconcentration technology.
"ProfIC 10" features intelligent system components such as iPump and iDetector and provides space for a total of three iColumns.
Numerous sample racks are available for volumes in the range of 0.5 - 500 mL for the 858 Professional Sample Processor – Pump – Injector. As a rule, only small volumes with a maximum of 1 mL sample are required for matrix elimination and neutralization.
