The Metrohm 797 Computrace Voltammetry System offers sub parts per million limits of detection at a fraction of the price of Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma (ICP).
With over 250 tried and tested applications, the 797 offers the user cost effective analysis together with simple to use instrumentation Whole suites of trace metals can be analysed together in a single short run

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.
e.g:- Zn, Cd, Pb, Co, Tl, Ni and Co in waster water according to DIN 38 406.
The 797 offers sub parts per billion limits of detection by using the technique of Stripping Voltammetry: this technique firstly pre-concentrates the contaminants onto the electrode surface then once this enrichment step is completed, measures the appropriate metal contamination on the electrodes.
In addition to trace metal ions, the following anions and organics are also possible to analyse using the 797 :- Cyanide, Nitrite, Nitrate, Sulphide, Chlorinated Hydrocarbons, Formaldehyde, Vitamins C,B and E.
etc The 797 Computrace is ideally suitable for simple routine analysis, for 24 hours per day, seven days per week and all parameters needed for the quantitative evaluation are displayed in an easily surveyed manner within a few windows.
Furthermore to eliminate any matrix interferences the 797 can be connected to a Dosimat to allow automatic Standard Addition. Request a free brochure from Metrohm UK ...
