The 838 Advanced VA Sample Processor permits fully automated determinations of organic additives in electroplating solutions applying «Cyclic Voltammetric Stripping» (CVS) in combination with the 797 VA Computrace. Series of brighteners or of suppressors (levelers, carriers) can be analyzed unattended in a sequential procedure. The included sample rack can hold up to 56 samples.
The sample solution is transferred from the sample vessel on the rack of the 838 Advanced VA Sample Processor into the measuring vessel of the 797 VA Computrace via the built-in peristaltic pump for the determination of brighteners or by 800 Dosino for the determination of suppressors using the dilution titration technique. Further auxiliary solutions required for the CVS analysis are automatically added with additional 800 Dosinos. The attached 843 Pump Station rinses and empties the vessel after each analysis.
The 838 Advanced VA Sample Processor has a flexible method editor to adapt the analysis sequence to the user's needs. The separate keyboard gives access to the method editor as well as to all other instrument settings. During the analysis of a sample series the 838 Advanced VA Sample Processor is remote-controlled by the 797 VA Computrace.
Including accessories, sample rack, keypad and accessories for complete measurement station. Without rinsing equipment.
