Fully automated 797 VA Computrace system for the determination of organic additives by CVS in the routine lab
MVA-13 is our top-of-the-line system for the fully automated determination of organic additives in electroplating solutions by CVS (Cyclic Voltammetric Stripping). Using the 838 Advanced VA Sample Processor, 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. Different methods can also be combined in one determination sequence.
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, the intercept solution and brightener standard solution are added by model 800 Dosinos; the peristaltic pump of the 838 Advanced Sample Processor is used for automatic sample transfer from the sample vessel on the sample rack into the measuring vessel of the 797 VA Computrace. The attached 843 Pump Station rinses and emptyies the vessel after each analysis.
