Modular ion chromatography anion system with chemical suppression, sample preconcentration and matrix elimination
Usually it is not the analysis itself that causes problems, but rather the sample matrix in which the analysis is to be carried out The Mic-6 Advanced modular anion system with chemical suppression, sample preconcentration and matrix elimination simplifies sample preparation in two respects: on the one hand matrix effects can be eliminated, while on the other hand the preconcentration technique can be used to reliably determine low concentrations

Jonathan Bruce, Applications Manager for Metrohm UK, provides this comprehensive introduction to analysis of mercury in waters
The contaminated sample is transferred to the sample loop of valve B by the built-in peristaltic pump of the 766 IC sample processor.
The valve is switched and now uses deionised water, supplied via the 833 IC liquid handling pump unit, to transfer the sample to the preconcentration column located on valve A of the 820 IC separation centre.
At the same time the deionised water is used to rinse the contaminants from the preconcentration column.
These steps can be repeated as often as necessary.
When the enriched sample volume is large enough, valve A is switched and the sample is transferred to the separating column - now without the interfering matrix.
Matrix elimination significantly increases the working life of the anion and cation columns.
Sample preconcentration extends the range of applications.
