After the TN sample is filtered, it is pumped into the reactor. Oxidants R1 and R2 are first injected and subjected to high-temperature UV digestion to oxidize nitrogen in the water sample to NO3. The sample is then diluted with sodium hydroxide solution, followed by adding copper sulfate and barium sulphate to convert all nitrates to nitrite. Finally, SAA (sulphonamide) and NED (naphthyl ethylenediamine dihydrochloride) are added. The mixture is mixed thoroughly and reacted, the analyzer will measure the ABS value of red reactive material at 525nm and calculate the concentration of the sample based on the calibration data stored in the analyzer.
■ Compact modular design and small installation space of the equipment.
■ Low consumption of reagent, low secondary pollution, only 0.8mL of reagent is needed for single measurement, and the reagent can be replaced after 45 days.
■ The precision metering system is composed of imported multi-channel conjoined valve and high-precision peristaltic pump to give precision single-unit control, low failure rate, low operating cost, etc.
■ The automatic alarm mechanism has such functions as data overloaded alarm, insufficient reagent alarm, automatic diagnosis, and automatic resume operation of the system to restore power supply in the event of power/water interruption.
■ Large data storage space and user-friendly operation interface, large hard disk storage space to allow continuous storing of 100,000 historical data, a large touch screen to enhance easy operation and maintenance.
■ Can be easily operated by non-professional personnel after given with simple training.
■ Controllable water pump operation to allow free sampling time setting of water pump.
■ The equipment has a security management function to perform automatic recording and storing all control operations. The storage method is read-only mode.
■ It has a level 2 operating management authorization system where the system administrator can execute all system operations, but the general operators can only conduct daily routine maintenance and operations.
