Example of a ProcessLab VA/CVS System
This ProcessLab system is equipped with a built-in
potentiostat/galvanostat 797 VA Computrace thus
covering a further application field. Classical trace
analysis can be carried out using voltammetry (VA). In
addition, Cyclic Voltammetric Stripping analysis (CVS)
can be used for the determination of organic additives
in electroplating baths. As a result of the integration
of the 797 VA Computrace the analytical system is
simple and compact. This version is controlled by a
clearly structured ProcessLab software, which provides
a simplified user interface. It allows the start of defined
analysis sequences by a single button and in this way
ensures error-free operation of the system.
Typical VA applications are
• Trace metal ions, e.g. Cu 2+ , Cd 2+ , Zn 2+ and Pb 2+ in
drinking, sea and waste water
• Metals in salts and high-purity chemicals
• Cd 2+ , Tl + and other metal ions in electrolytes used in
zinc production
• Analysis of organics such as 4-carboxybenzaldehyde
in polyterephthalic acid (PET production)
• Free styrene in polystyrene
Typical CVS applications are
• Determination of organic additives such as brighteners,
suppressors and levelers in plating baths, e.g.
in acidic copper baths
