Under weak acid condition, cyanide and chloramine T will generate chlorine hydride, and then reacts with isonicotinic acid to produce glutaconaldehyde through hydrolysis, at last creates purple-blue compound by the effect of barbituric acid. Within a certain concentration range, the chromaticity is in direct proportion to the mass concentration of cyanide.
Features
Permeance measurement technology will not be interfered by chromaticity, suspended solids and bubbles
Special design of flow path and reagent proportion, high detection precision, low LLOQ (0.05mg/L)
Adopt Constant Temperature Fiber Technology and Light Intensity Compensation Algorithm, small drift for long-term operation
Small maintenance workload and low maintenance cost
Self-diagnostic function
Highly integrated valve terminal, each valve can be maintained, disassembled and cleaned individually
Use USB flash disk for software updating and data exporting, more convenient
