Voltammetry system for plating is
versatile
Voltammetry system for plating carries out classical trace analyses of metal ions or other analytes after calibration by standard addition or calibration curve down to the ultratrace range.
The 797 VA Computrace consists of a VA Stand with built-in potentiostats/galvanostats; these are connected to a PC via the USB port Control, data acquisition and evaluation are carried out by the PC software supplied; this runs under Microsoft WindowsT 2000 or WindowsT XP Professional

Process chemicals can be analysed on-line
Metrohm has combined the best aspects of laboratory and online systems to produce the 875 ProcessLab: a fully customised, automated at-line system for analytical testing.
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.
Fields of application - carrying out classical trace analyses of metal ions or other analytes after calibration by standard addition or calibration curve down to the ultratrace range (ppt) is one of the most important fields of application for the 797 VA Computrace.
Evaluation is carried out automatically and can be controlled and reprocessed at the PC.
Standard additions can, of course, be carried out automatically by using Dosinos.
Determining additives in electroplating baths - in the 797 VA Computrace the determination of additives in electroplating baths is possible for the first time.
All the necessary techniques for data recording, evaluation and calibration have been implemented in the software; methods for important, often used bath chemicals have already been optimized and preinstalled.
Only with the 797 VA Computrace is it possible to carry out CVS analyses and classical trace metal determination with a single instrument.
The 'Exploratory' mode for method development and training is characterized by an intuitive user interface.
After entering a few parameters a voltammogram can be taken; the effects of changing parameter settings on the curve can be seen directly.
A direct comparison of the voltammograms is the greatest strength of the 'Exploratory' mode.
It has been specially developed for training purposes in electrochemistry, but also helps in developing the optimal method for solving an analytical problem.
Proven working electrodes - the time-proven Multi-Mode Electrode (MME) or rotating disk electrodes made from various materials are used as sensors.
Curves and results are shown beside each other in a well-laid-out program window.
Printouts are made in predefined formats.
All results and curves can be transferred to the usual text and spreadsheet programs (Word, Excel, etc.). Request a free brochure from Metrohm UK ...
