The right system for every need
The MVA Systems (Metrohm VA Systems) are sets of instruments customized to meet particular demands. Choose the set that meets your requirements, connect it to a PC and a supply of nitrogen (if required for the particular system), and you are ready to go.
The systems provide different degrees of automation, depending on the number of samples to be analysed. They can be used as stand-alone or PC controlled systems.

AN-V-077 Nickel and cobalt in zinc plant electrolytes (concentrated zinc sulfate solutions)
|
|
Nickel can be determined in concentrated zinc solutions by adsorptive stripping voltammetry (AdSV) at the HMDE using ammonia buffer as supporting electrolyte and dimethylglyoxime (DMG) as complexing agent. The determination of cobalt does not work under these conditions as the very high Zn2+ concentration interferes with the Co signal. Therefore, an alternative complexing agent has to be used: α-benzil dioxime in ammonia buffer under addition of sodium nitrite.
