MVA-13: Fully-automated analysis 797 VA Computrace system for the unattended determination of organic additives by CVS in the routine lab by Metrohm AG

The MVA-13 is Metrohm’s top-of-the-line system for the fully automated determination of organic additives in electroplating solutions by CVS (Cyclic Voltammetric Stripping). Series of up to 56 samples can be analyzed for their suppressor content in a sequential procedure. The maximum number of samples in brightener determination is 28. The option for the method recalibration during an automatic run of a series of samples guarantees the highest possible accuracy and flexibility.

The system is based on the 797 VA Computrace with three 800 Dosinos for the automatic addition of auxiliary solutions. In the suppressor determination VMS, as well as the plating bath sample are added by the 800 Dosinos. In the determination of brighteners intercept solution and brightener standard solution is added by 800 Dosinos, the peristaltic pump of the 838 Advanced Sample Processor is used for the automatic sample transfer from the sample vessel on the sample rack into the measuring vessel of the 797 VA Computrace. The two attached 823 Membrane Pump Units rinse and empty the vessel after each analysis. The whole analysis sequence is controlled by the 797 VA Computrace software.

The system accessories includes all required accessories with the rotating platinum electrode as the standard working electrode.
