Control of nickel plating baths
Metrohm ProcessLab is a new at-line analyser for electroless nickel plating baths, that continues the success of the Titrando range of laboratory titrators
The Metrohm ProcessLab provides at-line analysis of nickel, hypophosphite and alkalinity in electroless nickel plating baths The system uses well established hardware and software, including the Titrando titrator and tiamo software

ProcessLab-VA/CVS - the innovative process monitoring solution Voltammetry (VA) and Cyclic Voltammetric Stripping Analysis (CVS) are now available for routine analysis in the plant
Advantages to the process industry are manyfold.
* The industrial PC and I/O controller for sending information to process control systems.
* ProcessLab can be used at several different points in the manufacturing process.
The electroless nickel layers are normally nickel-phosphorus alloys.
For the reductive chemical deposition of nickel with phosphorus inclusions, sodium-hypophosphite is used as the reducing agent (reductant).
To apply even nickel layers to the workpieces, the content of nickel, reductant and the alkalinity have to be determined periodically.
For the determination of the ingredients an automated ProcessLab system is used.
All liquid handling steps such as taking sample aliquots, dosing of reagents, titration and cleaning are performed by pumps and burets controlled by ProcessLab.
A sample aliquot is transferred either to the vessel for alkalinity and nickel analysis or to the vessel for reductant content determination. Request a free brochure from Metrohm UK ...
