Total nickel online analyzer
AMT-TN500 total nickel online analyzer participated in the preparation and test of Guangdong landmark "Nickel Water Quality automatic online monitoring instrument Technical requirements and detection methods", and fully met the requirements. Detection principle: Under the condition of high temperature, sodium persulfate was added to dissolve the water sample to remove the interference of organic matter, and the organic nickel in the water sample was converted to inorganic nickel, ammonium citrate was added to eliminate the interference of iron ions, and iodine was added to oxidize all the nickel into trivalent nickel, and the color developing agent butanedione oxime was added to react with nickel to produce a wine-red soluble complex. Finally, disodium EDTA was added to eliminate the interference of iron, copper and cobalt plasma. The absorbance was measured by the analyzer at 525nm wavelength, and the concentration of total nickel in the sample was calculated according to the correction curve. The measurement principle fully conforms to the national standard "GB11910-89 water nickel determination butanedione oxime spectrophotometry".
The new measurement technology is not affected by the interference of large chroma, more suspended matter and more bubbles;
High reliability, strong anti-interference ability;
High detection accuracy, high resolution (0.001mg), small long-term drift of the instrument;
With one-key self-test function and self-diagnosis function;
Single channel high integrated valve island, single valve maintenance, disassembly and cleaning;
Extensible all-weather networking function to monitor the running status of the instrument anytime and anywhere;
With alarm function, quality control function and counter-control function;
Less reagent consumption, waste liquid separation, environmental protection and low operating costs.
