This product adopts the isonicotinic acid-barbituric acid spectrophotometry method. Cyanide and chloramine-T can generate cyanogen chloride under the action of active chlorine, and then react with isonicotinic acid-barbituric acid reagent to generate purple-blue compounds. The color change of the solution is proportional to the concentration of cyanide in the water. The concentration value of cyanide can be obtained by color development photometry.
The instrument adopts the homogenous purge automatic pre-treatment method to avoid the influence of interfering ions, turbidity and chromaticity in the water sample on the test results.
The constant current absorption method is adopted, with low detection limit, high accuracy and good stability.
It has has many functions, including standard sample verification, zero point verification, span verification, zero point calibration, standard sample calibration, automatic calibration of working curve, and automatic test of spike recovery rate.
It can be controlled remotely.
It has automatic fault alarm function, such as component failure alarm, over-range alarm, abnormal data alarm, reagent shortage alarm (water sample, distilled water, reagent), and can record and upload these faults.
It has the function of detecting the self-balancing of the optical path.
It has the functions of regular automatic cleaning and automatic calibration.
It has the function of automatic range switching, which can automatically adapt to changes in water sample concentration.
It can be applied to the automatic monitoring of municipal domestic sewage, water discharged from pollution sources, surface water and groundwater.
