mva ­ metrohm va systems complete voltammetry systems ­ the right system for each application the mva systems are ready-to-use complete packages custom-made to suit particular applications all you have to do is connect your package to a pc and off you go each mva system is supplied with all the necessary accessories mva accessory kits extend the possibilities of the mva basic system to suit special applications mva systems for voltammetric trace analysis mva-2 ­ partly automated routine trace analysis automatic addition of auxiliary solutions mva-2 is an easy-to-use va system for the routine analysis of traces of heavy metals in environmentally relevant samples or in production control just add the sample to the measuring cell from a pipet and start the analysis the rest of the determination takes place automatically this system is intended for users who require elegant and comfortable operation at an attractive price without having to use a sample changer mva-3 ­ fully automatic analysis of small series of samples mva-3 is the optimal 797 va computrace system for fully automated trace analysis one or two parameters can be determined in small series of up to 18 samples the samples are placed on the sample rack of the 813 compact autosampler transfer and analysis of the samples takes place automatically controlled by the software of the 797 va computrace mva systems for the cvs technique mva-12 ­ our recommendation for the determination of additives by cvs partly automated 797 va computrace system for the comfortable determination of additives by cvs mva-12 is the standard system for the routine determination of organic additives in single samples without a sample changer it allows the determinations to be carried out comfortably with the minimum number of actions needing to be taken by the operator the automatic addition of auxiliary solutions such as vms intercept or standard solutions is carried out by 800 dosinos for the determination of brighteners only the sample has to be added manually even this is automatic when suppressors are being determined if the optional rinsing equipment is used then the measuring vessel can be rinsed automatically after each determination mva-13 ­ fully automatic determination of organic additives in series of samples fully automatic system with sample changer for cvs analysis in the routine laboratory mva-13 is our high-end system for the determination of additives in electroplating baths with the samples being presented automatically by the 838 advanced va sample processor the suppressor content of up to 56 samples can be determined when determining brighteners up to 28 samples can be analyzed the possibility of recalibrating methods within a series of samples guarantees the highest degree of accuracy it is also possible to combine different methods in a single measuring procedure two 823 membrane pump units are used to automatically empty and rinse the measuring vessel after each sample 12
