MVA Systems for VA trace analysis

MVA-03 797 VA Computrace fully automated for trace analysis

MVA-03 is a fully automated analysis system for voltammetric trace analysis and education. This system is the optimum solution for the automatic investigation of small sample series that must be analyzed for one or two analytes in a single analysis run. The system is comprised of 797 VA Computrace, 863 Compact VA Autosampler and two 800 Dosinos for the automatic addition of standard solution and supporting electrolyte. Up to 18 samples can be investigated automatically, precisely and reproducibly.

The system is supplied with extensive accessories for a complete measuring site setup, including VA Computrace software and electrodes: Multi-Mode Electrode pro (MME pro), Ag/AgCl reference electrode and Pt auxiliary electrode.


 
MVA-03 797 VA Computrace fully automated for trace analysis

The software of the 797 VA Computrace controls the complete analysis sequence. The samples are placed on the sample rack of the 863 Compact VA Autosampler, and the rest takes place automatically: the transfer of the samples into the measuring vessel with the built-in peristaltic pump, the voltammetric determination with the automatic addition of all of the auxiliary solutions by using two 800 Dosinos and the automatic rinsing with the 843 Pump Station. The reproducible and efficient rinse minimizes carry-overs and thus enhances the accuracy of the determinations. In order to increase the number of auxiliary solutions, one additional 800 Dosino can be connected directly, as can four additional ones by using an 846 Dosing Interface. A maximum of seven 800 Dosinos can thus be used.
