797 VA Computrace is a modern voltammetric measuring stand that is connected to a PC via a USB port. The PC software provided controls the measurement, records the measuring data and evaluates it. As a result of the well-laid-out program structure the operation is unbelievably simple. The newly designed built-in potentiostat with galvanostat guarantees the highest degree of sensitivity with reduced noise.
Voltammetry system for the determination of organic additives in electroplating baths by Cyclic Voltammetric Stripping (CVS) and for training. Complete accessories with all electrodes for a complete measuring system: rotating platinum disk electrode (RDE), Ag/AgCl reference electrode and platinum auxiliary electrode.
797 VA Computrace – Manual or automated
Even without additional accessories the 797 VA Computrace represents a fully functioning analytical system that satisfies the highest demands regarding accuracy and sensitivity. An even higher degree of comfort can be achieved with the help of various accessories.
Automatic addition of auxiliary solutions with 800 Dosinos
The voltammetric determination takes place by standard addition or calibration curve und and can be carried out automatically if 800 Dosinos are used. Connections are available for a maximum of three 800 Dosinos. Of course, all other auxiliary solutions such as buffers or complexing agents can also be added automatically.
Fully automatic analysis of small series of samples with the 813 Compact Autosampler
The 813 Compact Autosampler enables fully automatic trace analyses. It is suitable for the precise and reproducible investigation of several samples. The sample rack accommodates a maximum of 18 samples. The built-in peristaltic pump of the 813 Compact Autosampler transfers them from the turntable into the measuring cell of the 797 VA Computrace, where they are analyzed.
838 Advanced VA Sample Processor – fully automated CVS analysis
In combination with the 838 Advanced VA Sample Processor it is possible to carry out fully automated determinations of organic additives in electroplating baths. Up to 56 samples can be analyzed for their suppressor content; the brightener content of up to 28 samples can be determined automatically. The 838 Advanced VA Sample Processor is also suitable for trace analysis as a matter of course.
Automatic rinsing of the measuring cell with 772 Pump Units or 823 Membrane Pump Units
Rinsing and emptying the measuring cell after each analysis can be carried out automatically by two 772 Pump Units or 823 Membrane Pump Units. This option is available for both manually operated systems and, of course, for VA Computrace systems with an Autosampler. The reproducible and efficient rinsing process minimizes carryover and in this way increases the accuracy of the analyses.
Autodatabase
The analysis data can either be stored individually on the hard disk or the Autodatabase software can be used to store it in a database with report generator. With Autodatabase all the data can be assessed at a single glance and individually arranged printouts can be generated.
