-Working principle:
Total phosphorus detection: Potassium persulfate is used as an oxidant to dissolve the water sample at 120 ℃ for 30 minutes, converting phosphides into phosphate ions. The total phosphorus content of the water is detected using molybdenum blue spectrophotometry (measurement wavelength: 700nm).
Total nitrogen determination: Potassium persulfate is used as an oxidant to dissolve the water sample at 120 ℃ for 30 minutes, converting nitrogen compounds into nitrate ions. The pH of the sample solution is adjusted to 2-3, and the total nitrogen content in the water is detected by UV spectrophotometry (measurement wavelength: 220nm, 275nm turbidity correction: A=A220-A275 × 2).
COD (UV) determination: Dual wavelength spectrophotometry (UV 254nm, visible 546nm).
-Application industry:
The NPW-160 total nitrogen analyzer/total phosphorus detector is mainly used for automatic monitoring of total phosphorus, total nitrogen, and COD in surface water, tap water, municipal sewage, or other special occasions.
-Instrument features:
The NPW-160 total nitrogen analyzer/total phosphorus detector is equipped with a multi wavelength detector, which can measure three indicators: total phosphorus, total nitrogen, and COD (UV).
The independently designed heating and decomposition device, as well as the integrated design of digestion measurement in the total phosphorus/total nitrogen analyzer system, simplify pipeline connections.
The NPW-160 total nitrogen analyzer/total phosphorus detector has a built-in CF card, and the data can be stored for a long time.
Equipped with a Chinese touch screen operation interface for fast and accurate reading, coupled with wireless transmission function, intelligent and reliable.
Low reagent consumption and waste liquid discharge, low operation and maintenance costs, and minimal secondary pollution.
