Online ion chromatography from Metrohm has enabled tighter process control of acid pickling baths, as the final cleaning stage prior to metal plating
Whole suites of trace metals can be analysed together in a single short run.
For example it will measure 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 797 is also able to analyse for the following anions and organics:- cyanide, nitrite, nitrate, sulphide, chlorinated hydrocarbons, formaldehyde, vitamins C,B and E.
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 ...
