On-line Wet Chemistry Analyzer


VPA® Voltammetric Process Analyzer


The VPA® is available as a single-parameter unit or as a multichannel configuration (up to 6 channels). Note: one "channel" represents one single stream with one single parameter measured in one specific measuring range. Likewise,  a 4-channel configuration can measure for example two types of heavy metals with each of them having two measuring ranges. Several combinations are possible, according to your application.

Stripping Voltammetry, as incorporated in the new analyzer system, is considered as one of the most sensitive techniques for the determination of trace metals, and enables you to detect and measure the elements of relevance in all sorts of water matrices, from the lowest (µg/l) ranges up to highly contaminated (g/l) samples. The method is also insensitive to interference, from which colorimetric determinations can suffer.
