The AQUA-500CN Cyanide Online Analyzerr is developed based on Ion-barbituric acid spectrometry technology. Under weak acid conditions, cyanide and chloramine T will generate chlorine gas, which then reacts with isocyanic acid to produce glutaraldehyde. Through hydrolysis, a purple compound is formed, and finally, it reacts with barbituric acid to generate another purple compound. Within a certain concentration range, the chromaticity is directly proportional to the mass concentration of cyanide.
Measuring principle
Ion-barbituric acid spectrometry
Features
• Permanent measurement technology is not affected by chromaticity, suspended solids, and bubbles
• Special flow path and reagent ratio design, high detection accuracy, low detection limit (0.05mg/L)
• Utilizing constant temperature fiber technology and light intensity compensation algorithm, minimal drift during long-term operation
• Less maintenance work and low maintenance cost
• Self-diagnostic function
• Highly integrated valve terminals, each valve can be individually maintained, disassembled, and cleaned
• Using a USB flash drive for software updates , data downloading is more convenient
• Easy to use touch screen , modular design; can work in offline mode, not affected by incorrect operations
• Quality control function, equipped with parallel sample testing, standard sample verification, and standard sample recovery rate detection
• Reverse control function: Automatically calibrate the instrument through flow rate, pH value, and other methods
• Data storage for up to 10 years; supports simultaneous uploading of two different protocols
Application
