Online ammonia nitrogen analyzer and online total phosphorus analyzer for water quality:

Colorimetric measurement parameters:

Total phosphorus, phosphate ions, ammonia nitrogen, nitrate, nitrite, sulfide, chlorine gas, chlorine dioxide, cyanide, hydrazine, phenol, aluminum, copper ions, iron ions, manganese ions, nickel, hexavalent chromium, cobalt.

Measurement object: Ammonia nitrogen in water

Method description:
According to different pH values, ammonia nitrogen is composed of ammonia nitrogen ions or ammonia gas. When the pH value reaches 12-13, ammonia nitrogen ions will react with hypochlorous acid ions and salicylic acid ions in the sodium ferrocyanide catalyst

Should catalyze the formation of blue compounds. The absorption band is 650nm. The linear range of this method is 4mg/L. There will be a deviation of -5% at 5mg/L.

Online total phosphorus analyzer for water quality:

This product is a true online analyzer in the sense of the internet.

This product mainly uses colorimetric method to analyze ammonia nitrogen and total phosphorus in water, and the input and operation data browsing are all operated through the touch screen.

Measurement object: Total phosphorus in water

Method description:

In natural water and wastewater, phosphorus almost exists in various forms of phosphates, which are divided into orthophosphate and condensed phosphate(pyrophosphate, pyrophosphate, and polyphosphate) and organic bound phosphates (such as phospholipids) They exist in solutions, humic particles, or aquatic organisms. Only orthophosphate can be measured by colorimetric methodTherefore, all other forms of phosphorus need to be hydrolyzed or oxidized beforehand in order to be converted into orthophosphate.

In view of this, persulfate and sulfuric acid were first added as oxidation reagents to the sample, and then heated to 90 ° C for 15 minutes under ultraviolet irradiation for digestion. To digest, air was continuously introduced into the digestion chamber

After digestion, the sample was detected using the molybdenum blue method, and interference was eliminated after digestion.
