The combination of the 850 Professional IC, 858 Professional Sample Processor, Dosino and Magicnet software from Metrohm offers a variety of automated ion chromatographic techniques.
The instrument combinations are available as anion, cation or dual-channel systems.
Calibration is straightforward and requires only one multi-ion standard.
Inline calibration allows users to calibrate in the ppt range by using just one stable standard solution at the ppb level.
By switching the valves one, two or even more times, different calibration concentrations at the ultra-trace level can be created with high reproducibility.
The inline preconcentration technique uses a preconcentration column and is ideally suited for trace analysis in complex matrices, especially when combined with matrix elimination.
Besides facilitating the preparation of g/L to ng/L calibration graphs, Metrohm's techniques are capable of logical decision making.
Therefore, Metrohm's Partial Loop technique allows samples with a wide concentration range to be injected without previous manual dilution.
In contrast, Metrohm's inline dilution technique, after the first sample injection, compares peak areas; calculates, if necessary, the dilution factor; and dilutes and automatically re-injects the sample.
Metrohm's inline techniques allow users to rationalise the time-consuming, error-prone and cost-intensive manual preparation of standard solutions.
