884 Professional VA semiautomated for CVS

884 Professional VA semi-automated for CVS is a convenient high-end routine analyzer for determinations of organic additives in electroplating baths with "Cyclic Voltammetric Stripping" (CVS), "Cyclic Pulse Voltammetric Stripping" (CPVS), and chronopotentiometry (CP), or voltammetric heavy metal determinations with rotating disk electrodes. The proven Metrohm electrode method combined with a completely new design of potentiostat/galvanostat and the extremely high-performance viva software opens up new perspectives in CVS. The potentiostat with a certified calibrator readjusts itself automatically before each measurement, thus guaranteeing maximum precision. The integrated temperature measurement input allows you to monitor the solution temperature during the measurement.The instrument can also be used to perform voltammetric determinations with the Multi-Mode Electrode or the scTRACE Gold. The replaceable measuring head enables rapid changes between various applications with different electrodes.Two 800 Dosinos (supplied) permit the automatic addition of auxiliary solutions during the determination, e.g., VMS, standard solutions or samples for the Dilution Titration technique (DT).The viva software is required for control, data acquisition, and evaluation.The 884 Professional VA semiautomated for CVS is supplied with extensive accessories and measuring head for rotating disk electrodes. Electrode set and viva license need to be ordered separately.

The 884 Professional VA system: for all voltammetry and CVS applications

The 884 Professional VA covers the entire range of voltammetric analysis from voltammetry and polarography to Cyclic Voltammetric Stripping (CVS).

This system can be used to analyze:

  • trace levels of, e.g., cadmium, lead, nickel, cobalt, or iron, in sea water, salts, and high-purity chemicals,
  • organic additives, e.g., suppressors, brighteners, and levelers, in electroplating solutions (by CVS),
  • various transition metal ions in water samples,
  • additives and impurities in electroplating solutions,
  • copper and iron in boiler feed water,
  • ultra-trace levels of metal species in sea water,
  • and more.

Save time and improve security with automation

Professional VA/CVS systems can be customized with automation and liquid handling modules.

User interaction can be reduced by using Metrohm’s Dosinos for automatic dosing of sample and auxiliary solutions for more convenience and measurement security. You can further complete your system’s liquid handling with pumps for automatic rinsing. Optional level sensors send out timely warnings when waste containers are full and prevent them from overflowing.

You can get your system exactly as you need it:
