The Professional VA cover the entire range of voltammetric and polarographic analysis. These systems can be used to analyze, amongst other:

  • Trace levels of, e.g., cadmium, lead, nickel, cobalt, or iron, in sea water, salts, and high-purity chemicals
  • 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
  • Organic additives in plating solutions with Cyclic Voltammetric Stripping (CVS)

The compact Professional VA allow you to save bench space in your laboratory. But what happens if you perform more than one application? No problem! Simply exchange the measuring head and continue with your analysis.

Options and upgrades

Increase your sample throughput

Your Professional VA system can be expanded with various automation modules to increase throughput, accuracy, and reliability of your analyses:

  • Dosinos for automatic reagent and sample addition
  • Sample processors for fully automated analyses of up to 56 samples in one run
  • Pump stations for automatic rinsing of the measuring vessel
  • Level sensors for sending out warnings when waste containers are full and preventing them from overflowing
