Unique inline sample preparation technique
QC inline sample preparation technique for the analysis of calcium in milk using ion chromatography.
Iodide levels in milk and milk powder can be easily analyzed using anion chromatography with conductivity detection after chemical suppression.
Milk is of a quite complex constitution.
Especially the fat globules and casein micelles account for some unwanted matrix effects.
Time consuming external sample treatment procedures are no longer necessary if you use Metrohm's superb Inline Sample Preparation (MISP) for ion chromatography.
The matrix of milk is removed fully automatic by inline dialysis prior to sample injection.
Analytical System: Compact ion chromatography system containing the 861 Compact IC and the 838 Advanced IC Dialysis Sample Processor MIC-7 Compact The For routine tasks and detection limits down to the ppb range, the combination of the 761 Compact IC with the 838 Advanced IC Dialysis Sample Processor is the optimal solution whenever contaminated samples have to be measured.
Dialysis is the method of choice whenever particles, oil droplets or coarse organic contaminants have to be kept away from the whole IC system.
The cellulose acetate dialysis membrane provides the necessary security without limiting the reproducibility and precision of the measurements.
As two valves are required for the dialysis, the 761 Compact IC is extended by one valve with the 812 Valve Unit.
The system is controlled by the IC Net software.
The separation column used is the Metrosep A Supp 5 - 150 separation column .
