4330 - Voltammetric Analyser

The specialist for heavy-metals analysis


the 4330 Analyser

The Model 4330 Voltammetric Analyzer is a combination of three electrochemical instruments in one.  Thanks to the evolution of electronics and firmware, we have been able to combine all modern voltammetric techniques with Potentiometric Stripping analysis (PSA) and pH measurement.

Trace analysis of heavy metals and organic compounds down to ppb (ug/L) levels will easily be accomplished by the most appropriate technique and electrode.
The integrated cell stand offers unrivaled versatility, thanks to the wide choice of batch/flow cells and electrodes, from classical hanging mercury drop and solid electrodes to modern rotating disk and screen printed electrodes.

Automatic quantitative analysis is then made easy by integration with an Amel 235 Automatic Dispenser.
This combination will allow you to perform routine analysis by a simple button touch as well as research work on the same instrument.

The instrument is supplied with the new VA_peak software for Windows.
