Voltammetry systems offer low price, low running costs and compact dimensions plus the ability to carry out trace metal analysis with high sensitivity in electroplating baths.
Metrohm's Voltammetry systems offer low price, low running costs and compact dimensions plus the ability to carry out trace metal analysis, with the same or better sensitivity the AAS or ICP, but at a fraction of the cost! Determination of additives in electroplating baths:- Cyclic Voltammetric Stripping Analysis (CVS) and Cyclic Pulse Stripping Analysis (CPVS) are widespread methods used in the electroplating industry for the determination of organic additives in electroplating baths For many technical coatings, particularly in PCB manufacture in the electronics industry, this method forms an essential part of the production control process especially for acid copper baths and tin-lead baths

Determining water levels in lubricating oils
It is impoirtant to determine the presence of water in machinery lubricating oils, which is why Metrohm is offering its 831 KF Coulometer to give reliable results over a long period.
The quantitative determination of the additives is carried out utilizing their influence on the decomposition of the main component of the electroplating bath.
As measurements correspond to a process which is similar to the production process, the activity of the additives and the effectiveness of the electroplating process are measured directly.
Quantification of the various types of additives requires special calibration techniques; these are all implemented by our new 797 VA Computrace.
Brighteners are determined by using the Linear Approximation Technique (LAT) or the Modified Linear Approximation Technique (MLAT).
Dilution Titration (DT) is used for the determination of Suppressors.
With CVS or CPVS the concentration of the additives can be determined exactly.
The effective concentration of the particular additive in the bath sample is shown directly on the printout in ml additive per litre of bath.
The means that topping up to achieve the set concentrations can be carried out very exactly.guaranteeing continuous interference free operation. Request a free brochure from Metrohm UK ...
